Large Vapor Leak

Post by DiverDave »

I had a large vapor leak (Mal) and tried to find it first by making a gas cap with
a air coupling to pressurize it to a few psi , maybe to help find the leak ...
It did not .. but I fear it may have caused a sensor to adjust the timing belts
and off set the timing adjustment.

This is why I purchased the DataScan II and used it to try and set the timing , idle and re-learn.
But the re-learn did not complete .. probably due to the large vapor leak.

I have since downloaded the v2.52 software and yet tried it.

My question is did pressurizing the fuel tank set adjustments off and can this be fixed easily ?

I have had this problem before and it was a vacuum leak in the canister system. Check all lines going to your vacuum canister. I believe that is on the driver's side in front of the rear bumber. Lemme know.... :D

I had the same issue with gas smell in the cabin and it was a bad vent valve solenoid located on LH (drivers side) rear wheel by charcoal canister. Remove wheel for best access.
