The fuelpak is easy to unplug. I can try that and see what happens.

 

=========================

If by passing fuel pack doesnt fix it then it could in fact be an issue with O2 sensor/s seeming to have failed with codes that's simply a dirty o2 post 99k miles of use.

Since you said you got it running better/normal since washing it but code/sstill came back re-check connectors for o2 sensors to ensure they are clean of moisture/corrosion & are tight too.

Next do this, run a minimum of 1 full tank (2 tank better for your 99k mile motor) of Chevron " Techron " thats an injector & combustion chamber cleaner using a healthy of 1.5 oz perf gal which would be approx 9oz Techron (Concentrated) for a 6 gal tank.

Note: (Use the Techron that states it's the " Concentrated " version on label & not the cheaper version thats not as effective)

Since you have now removed excess carbon & debries from combustion chambers by running Techron (CONCENTRATED VERSION) that gets spit out at high temp in the motors exhaust over time & 99k miles thats deposited on the o2 sensor/s fouling /reducing their ability to work properly " NOW " it's time to run a healty dose of whats called " o2 and Catalytic Converter cleaner cleaner " or i some cases a cleaner thats labeled an " Emissions cleaner " which include o2's & cat to remove any carbon & or contamination from the fine wire on the 02's.

I have used the above procedure many times over yrs in situations like yours with EFI bikes and or cars that were spitting out codes for emissions ,bad o2's or bad-clogged cat converter etc with great results more time then not.

With approx 100k miles on your bike it sure cant hurt to run a couple tanks of Chevrons concentrated Techron (Strong dose of 1.5 oz Techron per gal fuel) and then 02 & cat cleaner after that to clean fine wire on the o2's because there is no doubt post 100k miles the injectors and or comb chambers could use it.

I run that combo 1X TO 2X YRLY which has resulted in all the motors/cars in the family always running nice & smooth with max fuel mileage & nice crisp throttle response with no hesitation too.

And best of all none of the family vehicles (inc my HD too) ever experienced any emission related codes and or never needed an o2 sensor , cat converter or injector replacement or repair on any of our older high mile cars which are, 98 Maxima with 170k miles,98 old cutlass with 207k miles , 07 PT Cruiser with 101k miles on it.

Then if after you do above cleaning procedure find there are still emissions type codes showing up clear them and see if they return or not.

If the emission codes don't return that tells you it was in fact dirty comb chambers that fouled the o2's ,but if emissions type codes return that could be a totally failed o2 sensor/s and or other issue in emissions/EFI system someplace that needs to be addressed.

BTW,to show just how good & effective my rec cleaning procedure is using techron here are a few more " Techron Wins " i experienced with same type issues.

A few yrs back My friends sons 2007 Hyudai with 80k miles on it had emission codes w-chk engine light that the dealer said required a new cat converter & 2 o2 sensors replaced to fix for $1000.

I told him to run a healthy 1.5oz per gal dose of concentrated techron thru a full tank of fuel along with cat cleaner after that and guess what,the chk engine light went out & it passed insp.

The chk engine or codes have not returned in his sons car since then/2yrs later which which cost him approx $30 to run the 2 bottle of cleaners i rec he run thru the car/motor.

Then my same friend inherited an 80 honda civic from hi father that had passed away,car was in great cond that had sat for long time & fuel had gone bad and was running like crap (couldnt idle and ran rough etc) even though he drained old fuel and installed fresh fuel & new fuel filter prior to firing it up and had put approx 100 miles on it with no improvement still running like crap.

Once again,i rec he run healthy dose of 1.5oz concentrated Techron per gal fuel and guess what,again the techron cam thru because he said after approx 150-200 miles it straightened out running nice & smooth and has been find since then avoiding a carb rbld.

Lastly,3rd car issue my same friend had was with chk engine light coming on was in his 2007 Honda Odessey with apporox 85k miles that was told by dealer had emission issues requring new o2's and likely new coverter too for $1,500.

Once again i said you know what to do ,run a healthy dose of concentrated techron along with cat converter & o2 sensor cleaner after that and guess what,once again the chk engine light went away .

Car passed insp no problem after that and had been fine for over a yr since then.

He now follows/does the same regime cleaning regime on all the car in his family because he has seen it work great 1st hand 3x times in a row.

He also said post doing the 1st cleanings like i rec he do when he had chk engine lights and or clogged carb issues that his cars/motors handn't run that smooth in quite a few yrs feeling as though they all had just been tuned up with new plugs etc when all he did was spend approx $30 to run injector /carbon combustion chamber cleaner and o2 & cat converter cleaner after that saving him $1000-1500 on 2 cars not to mention a carb rbld on the other too.

Saving him $1k-1,500 got me lunch @ McD's each time,lucky me!/LOL!!!

Let us know how this works out if you decide to try what i rec & if it doesnt work what was the root cause ,a completely bad o2 sensor & or other issues with emission system,etc.

I have never heard of a o2 sensor/cat converter cleaner. Are there any particular brands and where would you get it?

 

Lastnight I reset the codes and cleaned the connectors on the o2 sensors with electrical contact cleaner but didn't check the connectors for the fuelpak. I rode to work this morning, about 10 miles. I got to work and checked the codes and now I have a a po131, po132 and po152. I will probably disconnect the fuelpak and see if the codes come back. I don't know what else to do besides replace the o2 sensors.

 

=========================

They have been on the market for yrs from diff mfgs with most being pretty effective to chose what ever brand cat & 02 cleaner you can find at your local auto parts store.

Autozone by me caries it mfg'd by of all people MRGasket & Solderseal,just follow int on lab el for dose to run .

For example if its a 20oz bottle that says it can be use in up to 20 gals fuel the 1oz per gal max treat is it lowest least effective dose and many cars (not talking trucks with hemi's here!) mfg'd today have as little as 12-13gals to as much as 15-16 gal fuel tanks on avg making a stronger better cleaning ratio.

So with that in mind if for example you were using a 20oz bottle of cat & o2 sensor cleaner in a 15 gal fuel tank that would = approx 1.3oz cat cleaner per gal fuel, so in your case with suspected 02 issues i'd run a little stronger ratio of 1.5-1.6 oz cat & o2 sensor cleaner per gal fuel that should not be a problem.

Let us know how the techron & can-o2 sensor cleaning works out if you decide to try it because it sure cant hurt and could possibly fix too.

Actually Xieds reduce the voltage signal from the O2 sensors

 

If I misread all this, I apologize but the way it went down is:

You switched from xeids to a fuelpack and all went well.... ran great, no codes.

Then you washed the bike, and now it doesn't run well...

It immediately ran poorly, but gradually ran better....

Based on that timeline & symptoms, my first guess would be it's water in a connector ... I always suspect that last thing changed or worked on when a problem suddenly appears immediately after some work or repair...

First I would disconnect all O2 & fuelpack related connectors, clean them off with electrical contact cleaner, and when they are completely dry, reassemble them with dielectric grease...

Second, I would check the Fuelpack. I would run it without the fuelpack and see if that is the problem.

Third, I would try the Techron/O2 cleaner as suggested by wscott. At 99K, that would be a good maintenance protocol in any case.....

If all that doesn't expose the issue, I would clean/inspect the MAP sensor.

All the above will cost you nothing more than time and the cost of a couple cleaners that are good to have around the shop/garage. They can all effect the codes you're getting. Unless of course, it's the Fuelpack gone bad, which needs to be dealt with ASAP.

Only then I would look at the the O2 sensors themselves... It's just rare that both O2 sensors go at once... not impossible, just really rare...

Good luck with the fix...

 

My '07 Ultra was throwing a P0152, in addition it was idling so low it was almost impossible to keep running while stopped. That was 2 years ago, changed the O2 sensor, cleared the idle problem, no more codes, and I check at the end of every ride.

 

========================

" I don't know what else to do besides replace the o2 sensors "

Dude,Your kidding right?/Geesh!/LOL!!!

AH,just busting your chops!

Anyway,After taking the time to write out detailed instructions on how to do my rec 2 step cleaning procedure along with mult testimonials for you to see what i rec has worked out for me why not simply try the 1st cleaning procedure i rec to clean excess carbon & contam from the combustion chambers & then after that try the 2nd cleaning i rec using cat & o2 sensor cleaner to remove carbon & contamination from the 02's that in many case cleans the o2's well enough to stop getting chk engine lights and emission type error codes too.

So before going any further & or spending considerably more money why not follow the steps exactly like i rec in my prior post in this thread to see if it helps your bike?

1st run a full tank (if poss 2 tanks would be better with 100k miles) treated with Chevron Techron (States " Concentrated " on label!) of 9oz for 6 gals fuel and then a full tank treated with the cat & o2 sensor cleaner too @ the dose rec i already stated in my post ans your question on where to get it etc.

If possible it you would best cleaning to run those tanks of fuel for both cleaning procedures at higher speeds/higher cruise rpm on open road because that will generate hotter ex temp and more exhaust force /CFM flow going thru the exhaust system at the same time too setting up best case situation for max cleaning efficiency in the engine and then on fine wire the 02's are made of too.

Then after your done doing both cleaning procedures i rec above put on another 100 miles or so on a fresh fillup and then clear the codes again & go for a nice 50-100 cruise to see if chk engine light comes on again & or if emissions type code relating to 0'2 sensors re-appear again in which case you may need to replace the 02's due to being so gunked up for so long without cleaning srvc like i rec that they are past point of no return which could be the case.

But trying to clean them up using my 2 step cleaning rec costing approx $30 for the cleaning solutions is easy & cheap that at the very least with clean excess carbon & contam from combustion chambers-pistons-backside of intake valve along with also cleaning 0'2s too making the motor run smoother with better throttle response along with little better mpg too.

And best case would be if it also got rid of the chk engine light & or emission related error codes your bikes getting too.

Good luck and let us know how this turns out if you decide to try it with nothing to loose giving it a shot.

The bike ran poorly for 30 seconds or a minute after I washed it. That's when I checked and the codes were there.

I unplugged the connectors for the o2 sensors lastnight and cleaned them with electrical contact cleaner. Rode it to work and that's when the 3 codes came up. I just took the fuelpak off at lunch and will ride it home and see if the codes come back. Will probably stop by a auto parts store and get some techron cleaner and o2 sensor cleaner.
