Now it has really bad idle and stumbles like its misfireing. but when i accelerate over like 2500 rpm it mostly goes away Sidom Veteran / Moderator Mar 20, 2010, 9:19 PM Post #2 of 3 (1488 views) Re: Jeep in trouble Sign In If the miss wasn't there before the plug change, the 1st thing I would check would be the firing order. It should be 1 5 3 6 2 4 with a clockwise rotation. steve01832 Veteran Mar 21, 2010, 4:33 AM Post #3 of 3 (1486 views) Re: Jeep in trouble Sign In Firing order is a great place to start. Also, did you gap the plugs before install? Also, if there is a lot of sludge around the plugs, it is possible that one plug air gap got filled with sludge preventing spark from arcing across the electrodes?
