Not the gas cap

[willez GT]

I went to autozone about my check engine light on my 97 grand prix GT they said it was the gas cap so I replaced it but the light is still on any sugustions? :th_scratchhead:

Did you clear it?

Might take a few starts and drives for it to go away if that was the only problem.

while you are at it get a locking gas cap!

Could be any part of the evap system leaking.

if they said it was a gas cap it was prolly that stupid evap leak code. usually it is a gas cap but it can also be a rotted vacuum line or the canister purge. also do you ever keep the car running while pumping gas? this will kick the code. usually it will go out by itself but just have them clear it.

You can try unhooking the battery for a few hours to try clearing the code.

I had the same problem with my '01 GTP. A new gas cap did solve the problem.

Not all of the aftermarket caps seal correctly. I had that problem with mine, and it didn't clear with the aftermarket gas cap. After I took it in to a shop to be diagnosed, they replaced the cap with a factory one and it worked fine.

Yes,they can be very touchy...there is a factory spec for a gas cap...some of these crappy Chinese aftermarket parts dont cut it...Ford had so much trouble they went to no cap at all on some stuff...bottom line,spend the extra money,get a GM cap...
