When I hold it in 1st gear and give about 1/3 throttle, by the time it reaches 2,500 rpm it starts POPPIN like a mofo.
This is where I'm at:
Pulled CPS (it has 2,500 miles on it, but has shook out and may be damaged), cleaned and reinstall it.
Tried new MAP sensor, no change. I will return it tomorrow.
Re-routed the vacuum lines on the intake in a loop, as to eliminate any possible component leaks. Only components receiving vacuum were the brake booster and MAP, same problem.
I'm thinking my next step will be to replace the CPS. I have an old one (put a new one in when I rebuilt the engine 2,500 miles ago) that I think I'll try to put in and see if it fixes the problem.
Another thing to note is that it ran great until that CPS shook loose and came off. Ever since then its been giving me problems, so im PRETTY sure that would be the problem. I guess I just dont want to believe that the CPS would go bad just like that .
Any input?
