I need help, i have a 94 jeep grand Cherokee 5.2 that has a miss, mostly at idle. I have changed plugs, plug wires, dist cap, rot button, fuel filter, ect sensor, cts sensor, cold air intake and i think it has just gottin worse. What should i do next and the plug on the cts, can it only go one way or can it go both just in case i put it on the wrong way?

 

I have seen quite a few lower intake gaskets leak on these causing the ghost missfire. You pull the intake and flip it over and there is a panel there take the bolts out and the gasket is most likely blown out. The miss could also be a compression problem as well, a broken valve spring,head gasket and or piston rings.

 

Do a comp. test. It could be a burnt valve/seat problem.
It might be an injector plugged/sticking also.

ok thanks guys, i will take a look at all that now.

 

it still says that the coolant sensor is bad in the consoles, i have unplugged battery for 15 min and ran codes. Could it still not be working right or just is and it thanks it is bad?
