I have a 1995 SC 5-speed that currently has a little over 27k on it. I bought almost two years ago with right at 22k on it. Since then, I had a full (not including headers) SCP exhaust installed. Then I installed a ported MPII SC that I had previously bought for my other SC (automatic-currently 188k). Installation went well. Then early this year I bought and installed a BBK 75mm TB, a 76mm C&L MAF, and the SCP air intake setup. Somehow, it has developed a serious miss at high boost. Other than that, it seems to run fine, but it's frustrating when you want to open it up, to have it start coughing like a sick puppy. It still has the original plugs and wires, but they should be okay given their low mileage. However, once my broken wrist heals and I can work with both hands again, I will probably replace them. Any ideas on what's causing the miss? I only run premium gas. Could it be a vacuum leak? I am sure everything is sealed proper, but maybe something's leaking? Any help you guys might have is appreciated in advance.
