HI all,

I am having some hard times with my rexy.

We Just installed an EJ20K STI RA motor - First start up,it doesn't idle, I need to manually push the throttle to keep her going.

Once warm the car does idling at 1500rpm +/- - dropping down to 1100 and back up to 1500, this happens while idling, the cel comes on and off... obviously its seeking

It all started because the car was idling @ 1500 and I am fiddling with the idle air control value to try and bring it back down?? The Cel first appeared then. started i was moving it for idle adjustment.

most of the time the engine light is on.

Tomorrow I will do the following:

check error codes manually
Clean AFM
CLEAN IACV
reset ECU
post on forum

Whats a quick way to test the afm and o2 sensor?
