Hello, I have a idle problem. I am a mechanic and have had 4 other ase certified mechanics look at this car. This car is driving me insane, I have zero known vacuum leaks, the iac is operational I have used a known good ecu the car idles rough, starts hard, no matter hot cold or warm the problem is intermittent and I think the problem is fixed but out of no where the car starts all over with the idle problem. The code it keeps tripping is the o2 sensor left bank(lean) but smells rich. All parts that are good. (Vacuum lines, egr, o2 sensor, iac valve, maf sensor, fuel injectors, fuel pressure, intake manifold gasket, spark plugs, wires, ecu, distributor, rotor, cap, timing, gas is good in car, oil pressure, when car runs right it runs AMAZING, but it will always go back to the idle problem eventually. ANY ADVICE. Anything will help! Please contact me.
