i was yesterday to a german repair shop to adjust my fuel mixture,,and the guy toldme that he does not getting any signal from o2 sensor!,,
he said that a lot of times the oil temp sensor or switch are bad,,and it may do that,, so i looked up to mitchell how to check the oil temp sensor and the program say at warm idle unplug wire to the ground,,the car should go to 850 rpms,, but on my car is not going up,,none ,,no difference
so i check the wire from the sensor all the way to the ECU electronic control unit (or ECM electronic control module the same??) to see if wire is okay,with a light and ,,yap the wire is fine,,

here is what the program say:



what im thinking is maybe the ecu is al most bad.. i smell it inside it smells litlle burn ,,but all electronix small like that,,,

and a other think,,for the first time i took the dash with gadges out and the wire from o2 sensor was out and no light!,i put a light and put it in and now is on,,

i dont know what is next,,, and the engine is starting litlle hard also i have to press the gas for 3-5 sec to comeback to normall...

any ideas ,,thanks in advance
