It happen when I change the back motor mount. I had to take out my header to get to it and i had to unplug the o2 sensor. When i was done i put everything back together and now my check engine is on and my car start up is idleing from 500-1000 rpm which i like because before my rpm was very low 100-400 rpm anybody have a clue help me plz.

 

Count the blinks on the ECU. Come back and post the code for mre help.

 

I would check to make sure you didn't unplug a sensor anywhere since you were "monkeying" around in there.

 

k i got the part were it make my car sound funny its normal now. How do i check the check engine light? how do i make the check engine light blink to tell me the code? let me know thx

 

I guess some ECU's have the LED right on the ECU, the guy I bought my car from told me I have to cross two wires and the CEL light will blink. I still haven't found the wires he is refering to.

 

Pull back the carpet on the passenger side of the car and find your ECU. Turn the key on and count the number of times the LED light blinks.

 

thx guys the code was 6 and it was the ect engine coolant temperture thx
