Engine light comes on once and awhile, did a code read- (p0454 EVAP intermittent), delete code and now am annoyed, I want to know how to release pressure from fuel tank/lines. I want to replace the EVAP Vapor Canister Purge Solenoid and Fuel Tank Sensor. Just bought the parts ($145.00 CDN) and doing the removal and install myself.
