Car: 97 9000 Aero (auto )
I did search, but did not find any definative answers....
My car has been having a boost "fluctuation" for a month or so. Basically, no matter if the car is hot, cold, wet, dry, etc., the boost goes up and down under acceleration. It goes from the middle of the red down to the bottom of the yellow, back in forth in a consistant fashion. I have unpluged the APC solenoid, and the boost "hunting" ceases under base boost. I also changed the BPV into a BOV, and now that I can hear it I have noticed that the car ocassionally dumps boost during accel. This however does not seem to correlate with the fluctuation because the BOV hiss is not all the time like the fluctuation is. I really hate the thought of dropping $200 for a new APC sol. Anyone had similar issues?
