I have a 2001 grand cherokee larado with 4.0 motor. Every now and then you have no acceleration and the throttle body is poping' like it's back firing. I can pull over and cut off truck for 2 minutes and then start it back up and drive off fine. I have plenty of pressure coming out the exhaust.
have the same problem?
