I have a 2001 grand cherokee 4.0 6 cly automatic i had the motor rebuilt 2 yrs ago now after it warm's up i get a chack engine light on saying that it's misfireing on 1,3,5,6 cyl's and it is.i checked the plug's there ok.Ireset the computer i just found out when you kick it into overdrive it kicks down but like there's no gas or spark like it shut off but if you let off the gas a little it run's.Could it be the computer?
