Idle Hunting 500 - 1800 once it warms up..

**locote** · 23-12-2007 11:13 PM

I get no codes thrown at me cause im using a PFC...

Ive tried disconnecting the IACV and makes no difference to ilde but when i unplug and replug it i can hear it make a noise...

I also unplugged and repluged my O2 sensor and it doesnt change idle at all..

I tested out my GFs Integra when i unplug her IACV her car idles low and rough unlike my...
But i cant get her O2 sensor unpluged as its real tight and i dont wanna damage it.....

My hand controler showsa 0.02 voltage for the O2 sensor...
What voltage should it display???
And should it go up and down with the hunting idle if it wasnt O2 related???

disconnect your fitv, its located underneath your throttle body

Yep ive bypassed it..
I have a hose feding coolant straight to the IAVC and still same problem...

I put it back the way it was..
Was i meant to block off the air holes now that theres no coolant going thruough it???

This all just started straight after installing a skunk2 manifold...
I used new gaskets and used gasket sealer when the idle problem started (ipulled it all apart again)

PFC doesnt throw codes plug a stock ecu in and try that..

sounds like vaccumm leak. try placing you hand over throttle body and check for leaks.

maybe something wrong with the manual idol controll screw on your throttle body?

Exaclty what happend to mine, one of the hoses on my Sk2 TB had torn, and it sat at like 1800-2000rpm then u put your finger over the hole and all was good,

mine hunts up and down but...
I baught a new O2 sensor any how, try to eliminate that...
Ill check the TB after i install new O2 sensor.

**locote** · 24-12-2007 06:22 PM

Will that still throw codes??
