anyone have any ideas?I’ve had my 2004 mustang GT 5 speed for about a year now and I still can’t figure out this problem. If I drive it regularly and just cruise the car runs fine. But once I go 3/4 to WOT the car jerks and cuts in and out. Sometimes the exhaust will make a popping sound at idle (sounds like it’s missing). Also, on some starts the car will start and die immediately. Other times it will start and run rough for about 10 seconds but after that it’ll run fine.
any help I’ll appreciate it, I’m 18 so I’m still learning
