Hey guys, i recentlly have been having trouble with my liberty. its been acting weird like the lights dimming and flickering so i checked the batt and alt and the checked out good. but it still does it, then the other day my check engine light came on and the car was running funky so when and had codes read and it read random misfires car had 114k on it. what should i start doing after the spark plug changing?>

i just had the same problem, mine turned out to be a snapped valve spring in my first cylinder
buy a commpression tester and check that
if you dont have compression you may want to pull the valve cover or maybe the entire head.
pm me if you have any other questions

Have you gotten it fixed yet?

If not, what codes are you pulling up?

had a similar issue, got misfire codes primarily on the #6 cyl, moved the coil from the 6 to the 4 cyl and had the codes move to that cyl, replaced the coil and all is good now
