I verified that the bypass valve was working properly with no leaks in the diaphragm. I then removed the catch can from the system and hooked up the vacuum log to the PCV system per the Procharger installation manual. Logged the car again and the fuel trims were still off. The STFT were primarily negative but did not fit in the -1 to -3 range. LTFT were still high. I am going to order a leak detector but wondered if it would be worthwhile to pull the intake manifold and see if the gaskets were pushed out or if I can find any cracks in the intake itself? Gaskets would be an easy and cheaper fix. Even an intake isn’t outrageous.

I am a pretty good shade tree guy who can replace parts and do some modifications but a trained troubleshooter I am not. Strongly considering shipping the car to an expert so maybe I can enjoy the car this season.
