hi can anyone help me out? i just swap out my tired 5.0 motor for a ford racing gt-40 engine and i have been back to the shop that did the swap twice already and the problems still exist. the idle is horrible and stalls when put in gear, it shutters and jerk at low speeds, and the most scary part is the brakes suck now the pedal is hard like a rock. i was told it's the computer or the trans. i had both checked before the swap. the cam is a e303 and i am running a stock cobra intake with the stock throttle body and a one inch intake spacer. btw my car is a 1995 gt
