Service Engine Soon light ....

[audiophile]

Only now after changing the headgaskets does it come on!. When I get on it hard sometimes to pass someone, and shift into a lower gear, the service engine soon light comes on. It used to come on before if I get on it REALLY hard but only once out of about 100. Now it comes on 50% of the time. any suggestions? TIA.

save yourself the headache of trying to figure out what it is, and just use a scantool.

Hey, thanks for the reply. Can I buy one, and where? Or do I have to go to my chevy dealer?

thanks

any autoparts store will have a code scaner. if you dont know how to pull codes with a paper clip.
