Figured somebody here has some 2.9 wisdom for me. Got a '90 B2 for fairly cheap, primarily cause it doesn't idle all too well. Got all the vacuum leaks eliminated, replaced any sensors that have tested bad, still has a real bad idle, worse when cold, gets better when it warms up to temp, should note I hear an occasional "pop" in the exhaust, doesn't sound like a backfire, real subtle. I'm getting about 40psi fuel pressure, did a compression test and I got about 125-130 across the board. The motor runs like a champ driving down the road, just has a terrible idle. I've done almost everything I could think of, so anything to point me in the right direction would be great!
