New BPC valve for '97 Cse bad?
Posted by Mike H [Email] (more from Mike H) on Tue, 12 Jul 2005 12:15:01

On hard acceleration (flooring the accelerator) the turbo boost gauge will travel past the dashed lines into the middle of the solid orange band causing car to stutter when I need the acceleration the most. I'm assuming that the studdering is the APC system cutting out fuel in response to an overboost condition. I am also under the impression that a properly working APC system will prevent the overboost from occuring via the BPC valve.
I first replaced the BPC with a used one (without curing the symptoms,) and recently a new BPC (wtihout curing the symptoms.) So far, I've spent a lot of money on repairing this issue without any success.
Is it possible that the new BPC isn't working correctly, or am I mis-diagnosing this problem? All help is greatly appreciated!
