similiar thing happened to my suburban....i took it to auto zone out here, they check that stuff for free.......eneded up being smog stuff
Boy all I have to do is keep checking this site and I find all sort of information that is helpful to me. The check engine light on the 95 olds with 242,000 miles so far just came on. I want to use it as a parts car but my wife thanks I can fix it. If you don't have the money to take them to the shop you will learn one way or the other. I'm lucky I know a mechanic at an Oldsmobile garage; I give him $20 when his information helps me out and it works out pretty good. I had to replace an upper intake manifold and had no idea where to start, he said it’s a piece of cake, not for me but I got it changed. Kind of like the old saying about not what you know but who you know.
