OK guys I am having a problem with my idle all of a sudden. My car keeps shutting off when I let off the gas or come to a stop. I have a turbo charged 98 integra gs running hondata. It is tuned on the dyno and has been running fine for 4 months. Now it is wigging out and I'm not sure what to check. I am not throwing any codes. Anyone have any idea what could be wrong with my car? I have an extra idle control valve I can swap out but I'm not sure if that is the culprit. Any suggestions??

 

Make sure the screen on your idle air control valve isn't clogged with soot.

Doesn't sound like a Hondata problem if it has been working fine for 4 months.

Could be bad fuel pump, injectors, turbo, IAC, spun bearing....

Look at the mechanical weak links first as they are the weakest link. You can unplug your Hondata interface box and the car will revlimit at 4000rpm, but the ecu is reading a chip that unless you make changes to the rom image and reburn it will not change on it's own.

 

I have been experiencing the same problem. It only happens occasionally...upon decelleration and into neutral, the revs drop to 750, then sink and the car dies.

I have been blaming the DSM 450's (odds are the one DSM part is the one to go bad ), but possibly the FITV or IACV could be the culprit?

 

Soot?? he got a fire place in the intake manifold?? hehehe
