Thanks... I will try the codereader thing again. Im not really sure which cable on the battery to pull? cuz there are two of them. If its something different than those two I probably cant find it, it took me 20 minutes to find the thing to plug the thing into. I am trying really hard to learn about my car but I get discouraged cuz Im beginning to think that car stuff is a man's bussiness cuz I cant find anything or figure anything out lol. I know where the battery is and where to put oil thats about it.

My check engine light comes on and stay's on for like 30 secs. What could be up? Autozone said the check engine light had to be on, or they could not read the codes. I thought the computer stored the codes for awhile?

Hey Kelly, my 95 had similar symptoms. It would really suck when the light would go on and off because I'd take it to the shop and by the time I got there, it went off. Anyway, it ended up being the MAF sensor. The stock sensor went out and I made the mistake of just buying a stock rebuilt for $75, instead of upgrading. Well, good luck!

My mechanic said he thought it was goin bad...but he said running the computer test wouldnt tell us that it was goin bad he said its good until its bad. He said i needed to bring it over right when it was acting up and the light on which is never when Im near his house lol. Thanks for telling me that..... I guess i could just go ahead and replace the thing.

your maf sensor and all of that is next to your filter on the passenger side of the engine, in front of or maybe right next to the wheel well in the engine compartment. i can't remember if it says MAF on it anywhere, but all of that is easy to find right there. the electronics just plug right into the air tube that runs to the engine, small connector with a few wires. I'm assuming that's what they want you to tap, mine hasn't ever acted up yet. good luck kelly
