Default poor idle when hot... with solution...

2011 Street Glide 103

Thought I'd share a recent problem and solution...

Bike began having a problem with idle dropping down to 700-800 rpm and stumbling when hot. Eventually over several weeks problems progressed to not wanting to idle at all and check engine light would come on.... Code was usually p0505 and once showed po113.

I finally figured out that wiggling the wiring harness to the TMAP sensor would kill the engine.
The wire from the frame mounted plastic loom to the sensor was too tight!
No slack at all resulted in a 90 degree turn into the connector. This broke one wire inside the insulation.

I decided to avoid messing with terminating the BOSCH connector. I purchased one with pigtails already installed as that also resolved the issue of not enough slack!

(I purchased CONN-85722 from Ballenger Motorsports. It doesnt seem quite as heavy duty as the original, but a serviceable replacement. http://www.bmotorsports.com/shop/pro...oducts_id/1626 )

Hope this helps someone out!
Allen

Thanks for the post Allen, and good to hear you found the solution!
Being an electronics person myself, I really dislike when I see people do the same type of things with all sorts of electronic cords and then wonder why they'll have problems or shorts not too long down the road.
Cords don't like being bent hard and need slack!

I'm having the same issue, started out as sputtering while riding, and progressed to having a hard time just idling at startup and CE light coming on... wiggling the wires in there had the opposite effect for me: it idled regularly for a second or two, like if the connection was temporarily made, then goes back to very rough/low idle. Did you need to remove the gas tank to replace the harness? I was thinking of changing both the harness and the sensor... but after reading this and other posts, I think I will try replacing the harness only first and see if that works.

So this harness comes with the pigtail wires already attached? I replaced my sensor and when I jiggled the harness, the bike freaked out, sputtered and shut off... so it looks like the same issue you had. Do you know if HD also carries this part?

Thanks!

my bike died on the dyno with a MAP sensor code...guess I will be looking at this..

thanks, great post!

Just a follow up... I replaced the harness to the map sensor, and left a little more slack on the wires than HD did so that they won't bend as sharply at the connector and a little above that. That resolved the issue for me. Bike is smooth again.

Default choking out

It seems this could be the same issue here. I am less than mechanically inclined. My bike runs fine at high end but going through traffic in town or construction between 25 and 45 mph and and rpm running close or right at 2k it starts to choke out, high mph and rpm it is fine. 2002 Ultra Classic fuel injection.
I tried Seafoam but no change. I bought the bike as is and used. It is getting close to 30k but didn't want to do the $500 tune up just yet. I can also make the bike "cough or choke out" by rolling the throttle small quick turns in idle. It like coughs a puff of air, causing the engine to cut out for a split second. I know I will have to take it in but was hoping to at least get a clue what it could be and/or what it may cost. Several suggestions were like tip sensor, circuit breaker- whatever that is, ignition module at the end of the crank? Or maybe a bad fuel pump relay, if the bike is injected? Mapping? The bike did run fine for a bit but then started this issue.
The bike starts up fine, idles fine, does not have stock pipes and has a heavy duty clutch. Sorry for getting winded, no pun intended

Randy, i would get on Dynojet's site, find a dyno tuner near you, and ask them to to test it on the dyno, that way they can see what is happening.

i dont think a dealer can fix this by looking it sitting still

You can check to see what trouble codes it is returning with the steps below; this was how I found it was related to the map sensor - mine was returning map sensor codes. Also... while you're bike is running, wiggle the map sensor wires with a pencil or something and see if that changes how the engine runs. Could also be your map sensor is gunked up... mine was pretty bad, I was able to clean it up a bit with some MAF sensor cleaner, but I ended up replacing the sensor anyway, as I wasn't able to get it all the way clean, but I will spray that now as part of my regular maintenance... on my bike, I remove the air cleaner, open the butterfly and spray the sensor.

Otherwise, yea, have it checked out... that was going to be my next step if the harness didn't work.
------------------------------------------

The following procedure will instruct in retrieving*and clearing*ECM Diagnostic*Trouble Codes*and*TSM/TSSM*codes thru the Harley guage cluster as well as a list of codes.*

1- Turn*Ignition switch*to OFF & Run/Stop switch is to Run.*

2- Push*odometer reset*button in & hold.*

3- Turn*ignition switch*to Ignition and release the odometer reset button. Background lighting sould illuminate, sppedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear.*

4 - Push the*odometer reset*button once and you will see*the selection menu "PSSPt" with the first P flashing.*

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the*odometer reset*button one time. (from P to S to SP to t and back to P, etc.)*
P = ECM/ICM*(Electronic Control Module)*[EFI] /*Ignition Control Module*[Carbureted])*
S = TSM/TSSM (Turn Signal/ Security Module)*
SP =*speedometer*
T = tachometer*

6 - To get the DTC within an area of diagnostics, push and hold the*odometer reset*button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word “none” will appear if there are no DTC’s. Push the*odometer reset*button again to view additional codes if they exist.*

7 - Record the codes.*

8 - If DTC’s are not to be cleared, Press and release the*odometer reset*button. Part number of module will be displayed.*
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the*odometer reset*button ( longer than 5 seconds) until 'clear' comes up. Release the*odometer reset*button. Turn OFF the*ignition switch. Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to 9. If the code is current it will reappear.*

9 – Press and release the*odometer reset*button to continue to the next module.*

10 – Turn*Ignition switch*to OFF.*

On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.

"No Rsp" (no response) will also appear if the run/off switch is in the off position when doing this procedure.

04ctd and caberto thank you so much, Caberto--my goodness that was an awesome post, very informative about things I didn't even know existed. I know the dyno should do the trick but at $400 I will need to wait on that right now. I will definitely check the codes if I find any. You guys rock!
