sea foam in the intake. Remove the brake booster line and let it suck half the can in. Let it stall out or turn it off, and wait 30 minutes. Start it back up and run the **** out of it. It will smoke horribly.

Re: Car doesn't start right up.....

Ok Well ive been reading through the archives and ran into someone who had a problem with the charcoal canister, so I took my gas cap off and tried to start it and it cranked right up. Ive done it twice so far after letting it sit for an or 2, I also watched the fuel pressure guage closely and when it cranks it drops down to like 28-30 PSI for a split second then shoots back up to 40, I guess I'll change the fuel filter again and try tracing down the EVAP system problem.

Well I decided tomorrow instead of digging around under the car I'll just try and put a vented gas cap on and see if it works.
