The check engine light is on from around 1 month ago. I got 2 codes: P0141 OBD-II Trouble Code and
P0507 - Idle Air Control System RPM Higher Than Expected. Sometimes the RPMs boost out of control, this happens mostly when operating with the AC on, which it feels like takes too much power from the engine and therefore doesn´t perform well.
In the last 2 weeks my car has low acceleration and doesn´t reach highway speeds easily, running with low RPMs, 2500RPM max, very hard to reach 3000RPM sometimes to pass, with 4th shift.
I found that part of the problem might be a worn oxigen sensor, and I would like to know please if I could do it myself with common handtools, or for the whole problem is better to take the car to a auto service.
Thanks so much
have the same problem?
