at idle. With vac removed from fuel reg, pressure went to 43lbs, so assuming pump and regulator and filter are ok. When car is shut off, pressure holds for at least 30 min before starting to drop, so I think fuel reg and injectors are ok. I checked the map sensor, get 4.8v with key on engine off. If I create a vacuum it drops to 2.8, so that seems ok as well. Do not have test equipment to check mas air sensor, so I replaced it with no improvement. I also loosened the exhaust manifold to check for clogged cat, but that did not help. So I'm out of things to check. Any help would be greatly appreciated.
have the same problem?
