This problem has been going on for over a year and a half now. I had the fuel pressure checked 3 times and it was within specs. If the fuel pressure was fine would that mean the injectors,regulator are good? The filter has maybe 5000-6000 miles on it. How can I test the fuel regulator? As far as the cats possible being bad I will check that tonight when it's dark and see if there glowing. My other car that my dad drives now had the same problem. Which turned out to be a bad seal where the didtributor meets the timing gears. It used to run out at it's peak torque just like mine. The car looses power through it's power band. I live in Cal,so forgot getting a aftermarket exhaust. I have to have the nazi sniffers run my car in August.
