Trying to figure out why car is jerking. Started by pulling codes and got code 12 which is the MAF so I proceeded to remove the MAF and try another I had laying around from an NA Z i use to have. Once I replaced it I cleared the codes and checked for codes once again and it came back clear... NO CODES. However the car idles like Sh1t and still jerking under load.
What now? Check Injectors?? check fuel pressure? Do I have a boost leak?
What I can tell you is that the car will jerk at 3000 RPMs if I try to floor it.... if I try to pick up speed slowly its not so bad and if it does jerk it does it at about 4000 RPMs.
