eh, stupid questions are mandatory though. sometimes people overlook the absurdly obvious, i know i have been victim of this from time to time.


anyways, im lost, you dont know what code its throwing, but its throwing the o2 sensor code?

are you running open header by any chance or an aftermarket header/exhaust? the O2 sensor may not be warming up to operating temperature if it isnt a self heated one.

also, do you know the flow ratings at a given pressure of both sets of injectors? you may have possibly carbon fouled the sensor if too much fuel is getting dumped.

also, was there a change from hi-imp to lo-imp, or vice versa? i know you made mention of resistors, i thought the EF's had resistor boxes on the non-dual point injection cars.
