[QUOTE="leroyt10, post: 14631292, member: 166177"] I would recommend you monitor Long and Short trims while wiggling the FRPS. Have seen some fail internally and the press would spike to 70+psi. Also have seen the Canister purge solenoid stick open on some and allow vacuum from the engine to pull vapors form the Charcoal Canister, at any rate a good look at your data logs should help you weed through the problems.
