i think i am experiencing fuel cut. In 2nd 3rd and 4th gear at around 4500rpm my car like boggs out and stutters and doesnt want to go any farther. I replaced my map sensor and scanned the car with OBDII and no codes came up. Since everything i have done so far hasent worked im going to try one of mikes 3 wire fcd's. If the fcd doesnt work i really dont know what else to do. Help? Please?
