I have taken it to the dealer here 3 times over 6 months for this. They keep replacing things and charging me $$$ and the problem keeps coming back exactly the same.
I got fed up with them and bought an OBD2 scanner. One problem I see is that even when idling cold, the PCM reports that it is in closed loop mode. My repair manual says this should only be after the engine reaches "normal operating temperature". I cant seem to find anywhere what this normal operating temperature range is supposed to be. Do you guys know this?
The coolant temp reading seems to be accurate, starts low and slowly climbs to 200 deg F, where it stays steady. Do you guys think this closed-loop mode is the problem, or something else?
have the same problem?
