2009 iron 883 sluggish problem
any recommendations?
problem: open throttle = sluggish, it wants to cut off, sputters, its the best way i can explain it. sometimes i would need to open throttle to start it up.
quick fix i tried = i put fuel injector cleaner in the tank. checked spark plugs, battery is good, swapped out spark plug wires.
any help, thanks...

An issue like that is kinda hard to diagnose over the web, unless somebody has had a similar issue. How do you know the battery is good? Also bad fuel crops up now and then. Any amount of water/dirt in the tank can make EFI systems run like ****. Maybe an intake leak. Do you have a service manual? Does it clear out or just run poor in general? I posted the following on another members thread about his 883's problem...
the closest I could find in my repair manual under troubleshooting, is the following. "starts but runs irregularly or misses"-
spark plugs bad
plug wires
plug gap too close or wide
faulty coil, ecm, or sensor(tmap,ckp,et,or O2)
battery nearly discharged
damaged wire or connection at ecm, battery, or ign. coil
intermittent short due to damaged wire insulation
water or dirt in fuel system
fuel tank vent system plugged
air leak at intake or air cleaner
partially plugged fuel injectors
damaged intake or exhaust valves
weak or damaged valve springs
incorrect valve timing
Most of these are going to be a miss, not sure what kind of maladies a plugged or misconnected tank vent will cause, though. Your battery and connections are suspect as well I'd find a dealer who at least has a tech who says "sir, I've got to do some research on this one, and then reads the manual before he speaks to the customer about chit he's not familiar with.

sounds like a clogged filter, pinched fuel line, possible vaccuum leak. of course that is where I would start on a carbed bike. That EFI is a monster of its own. could be a clogged injector, bad fuel pump, or any combination of things. Could be as simple as a bad tank of gas. You could always try putting some fuel stabilizer in the tank and see if it helps.

1. Moved ECM. Are any of the wires loose? Check that.
2. You have an SE AC and V&H Shorts. Any ECM changes or could this weather be making it show itself more?

I would start with the easy stuff...do one at a time so you know which one fixed it.
Assuming you have already made sure you have good gas in it and have load tested the battery)
Change the plugs...they can "look" good but still be bad.
Clean or replace air filter
Clean the recessed posts in the coil where the plug wires plug in
Clean the connection where the wires run from the ECM and plug into the back of the coil
Check for an intake leak
(use dielectric grease on all the above electrical connections and put some in the ecm connection...it may have taken 500 miles for the connection to degrade since you moved it)
All the above are easy, fast and fairly inexpensive...if none of them fix it, gotta dig into the fuel delivery system.
Keep us updated...would like to know what you find the problem to be.
