wow...ive had the car for 4 years now i think and its just never run right. its always had a high rpm miss that i couldnt figure out. and it was fouling the number 1 plug all the time. ive changed everything on the car and finally this weekend decided to see if it was the injectors. i swapped out the number 1 injector with one that i knew was good and the thing runs like a champ now. no more miss and it actually sounds like a mustang and not a truck. i just had to tell someone because im so pumped to finally have fixed this thing
