Hi folks,
I have been a long time lurker in this forum, desperately need help to get this baby smogged, any inputs would be greatly appreciated!
The main problem is that it is running very rich (blowing huge white smoke which smells like fuel upon revving. It stalls especially easily during cold start.
However, once the car is warmed up, idling is very stable and smooth.
Recently replaced:
OEM New intake manifold gasket
OEM throttle body gasket
OEM New injectors
OEM Spark plugs
Performed smoke test multiple times, no visible leak from any vacuum hoses/ intake manifold gasket.
I used Autologic scanner (DME) and two fault codes were shown:
(022) 16 Idler actuator
(010) 0A Oxygen Sensor Control
I did research and could not find any information with regards to these two codes, regardless, I went ahead and replace a new O2 sensor. Cleared code and ran the scanner again, the only code left is (022) 16 Idler actuator.
I guess my question is, is a bad Idler control valve really makes the car running rich? Additionally, I tried disconnect the idler control valve sensor while the car was running and there was no difference in idling whatsoever. What else could be the problem of it running super rich? I would appreciate more opinions before I spend another $170 for a new idler control valve :(
Thanks for your time!
