The problem is a hesitation that seems temp. related. When I first start the car and give it a good run all is smooth (or so it seems). The more it runs the less throttle it takes to get this issue. At first I thought for sure the plug wires were bad because of the way it felt...as though something was holding it back and there are moments during acceleration where it clears out and really hauls along...then back to holding back....and clearing....and back and forth.
One thing I just remembered when I had the car hooked up to the scanner...the baro solenoid never changed from full vacuum even during boost. Think that has something to do with it...the car has no codes. Hmm...
Today I decided to un-screw my boost controller all the way out to minimum boost levels. The problem has seemingly gone away and the car accelerates at a smooth clip (I can still noticeably hear the swingvalve flapper fluttering away but not nearly as loud as before). So I'm thinking turbo related or exhaust....whether it be wastegate actuator, or turbo, or exhaust it's something there.
Ideas?
