I've got an EVAP trouble code, read at an auto parts store for me. How to proceed? I looked at the gas cap, there is a very minor imperfection in the rubber seal. I don't want to buy a replacement cap, just on the chance that's the problem.
How can I see where the associated vacuum lines run? Is there a manual (or diagrams) online? I just tried and can't spot the canister in this car, if there is one.
Any tricks or tips? Can I use something (maybe Saran wrap or something) to make a good temporary seal on the gas cap?
I did once do somewhat similar with a different vacuum leak, on my old 95 Beretta, but I no longer have a vacuum meter. So I'd just try a visual inspection of the lines if I can.
Thanks.
