I have a 1987 Dodge Shelby Lancer with a 2.2 that's been bored, stuffed with forged internals, ported intake and exhaust manifolds, walbro fuel pump, +40 injectors, newer fuel rail and FPR, rebuilt T2 Garrett, full 3" exhaust, factory intercooler and airbox system and a Stage 5 FWD Performance cal in it. A couple weeks ago (I am not driving the car everyday) I had a problem with the car reaching 4200-4300 rpms then stuttering like it was bouncing off a rev limiter. The car starts up fine, reaches normal operating temperature, doesn't blow any smoke, and idles smoothly, and no CELs are on. I thought I was having spark break up and replaced the plugs, wires, entire distributor assembly, and coil from my 90 Daytona, which are all good parts and take the Daytona out to redline all the time(this did not fix the problem). I replaced all rubber fuel lines and fuel filter back in June, and didn't have any troubles with it immediately following. A few days of toying with the car and it's situation, and I noticed the boost was not stopping 18 lbs like it should and going into the mid 20's. Has anyone experienced similar problems? I haven't had time to go home to work on the car recently and was trying to get some ideas for the next time I get a chance to work on it. A fellow TMer was leaning towards the possibility of a computer related problem. Any thoughts?
