Here is the deal. Got my car back from ford last week after they had to replace a cylinder head. I threw a plug, they said it was common but I think it was they did a poor job changing my plugs last month and were just covering their a$$.
Anyway, now when I try to accelerate and I am under 2000RPM, for example going 55 at around 1500 RPMS and push the gas any more then a little bit, the car seems to sputter and almost buck. Feels like its just trying too hard to speed up. If I push the gas only a little bit then it seems to be alright, its only when I try to give it a lot of gas.
I recently added the CAI and MAC Cat back, which I know reduces back pressure and causing loss of low end torque. Could this be causing the supperting when excelerating under 2000RPM?
