Car in sig, fully tuned, runs and idles great. Intermittently, when I roll to a stop the car will idle low and lopey, air fuels go stupid lean and sometimes it will die. The tune is fine, IAC is clean and functional, and FITV has been removed. Im leaning toward electrical, but have no idea. Anyone have a clue?

 

bump

 

The extreme lean condition could possibly indicate a problem with the O2 sensor. Any CEL?

 

same thing with my ek all the new shi$ i put in it nothen work Then i put a new T P S and fixed the problem..

 

The car is fully tuned on Neptune, and doesn't use an oxygen sensor.

 

Bad tune? Low fuel pressure? Any CEL codes?

 

Sometime it can be caused by the distributor, I have the same problem and I figured out that it could be caused by dirty injector or dirty fuel filter. Aslo check for the vacuum on top of your fuel pressure regulator, make sure everything is alright.

 

tune is perfect and has been for a year until this problem came up, cel is clean, fuel pressure is normal... unfortunately the problem is completely random. It will run beautifully for a while, then won't want to idle. Next I will try to log iat, ect, and **** next time it does it.

 

Honda are really bad on distributor, sometime they go and you don't know why, I had the same problem and that was is,
