I have a 2000 Cherokee with a junkyard motor. Jeep seems to be going thru spark plugs and misfiring. I bought the Jeep with the motor in it. It has 90,000 miles on it. What Could be causing the misfires?
Still have the 0331 head?
If the Check engine Light is ON, there is malfunction. Download the the Check Engine Light trouble codes and use your Factory Service Manual to perform the recommended diagnostics.
0331 and TUPY are cast into the heads near cylinder 3/4, all you have to do is look. If you don't know where to look, use the Google.
Did we ever come to a conclusion on define and explain "going thru spark plugs" ?
