I have a 93 that when i got it was running great. In driving it for a year several issues arose. I did the 130k service and loads of other maintenance. Car doesnt run right any more. What it does is starts and runs fine, then when i drive it its fine, until i put my foot into it then it sputters and runs incredibly rough until i back off the pedal. When not in boost i can redline it and its smooth as glass the whole way. Not until i get into boost does it fall on its face. I dont even know where to start with this. Ive had local mechanic tell me compression is fine, coils are fine, injectors are fine(i replaced one suspect one even), ive replaced knock sensor, temp sensor, fuel filter, and more. I jsut need a direction! I can post a video of the issue this weekend once i can start and drive it. HELP!
