Hi, greetings from Argentina, im having a very weird issue, when i start the car it idles perfectly but as soon as i move it 5 meters it starts stalling, idling at 600rpm, i did a vacum test it was all good, also i have no fault codes at all, if i let the car idle it can be there perfectly for 2 hours as long as i dont move it.. i cleaned the IAC can it be that? problem started just after i wired the wideband into the ecu folliwing the tutorial here in evolutionm, i returned everything back to stock but the problem continues, any thoughts? thanks very much

 

Does the car move freely? I mean...is there weired "rolling resistance"?

Have you tried another working MAF sensor?

I had a similar issue years ago intermittently when my car would experience load it would stall. The issue ended up being a bad MAF sensor.

 

Did you let your ecu relearn idle? Let it idle for ten minutes with all electronics off, such as lights, radio, fans, what not. Afterwards idle for ten minutes with everything on (highbeams, radio, fan, rear window defroster, etc).

 

sounds like a "load" issue. is it tuned?

 

thanks everyone it turned out to be a faulty IAC
