I've got a strange issue with my 1997 Aero. If I ease into the throttle, the boost seems to build more pressure, resulting in what I guess is "overboost". When this happens, it feels like a skipping feeling, like the car gets reduced to 2 cylinders. If I mash the throttle, it down shifts and takes off, but not with a proper amount of boost. I don't get it. Other days, the turbo seems fine. I've replaced the BPC Valve, and get the same result. But the skipping feeling is terrible, and has me quite concerned. Any ideas?
Thanks in advance.
