Hello, this video was extremely helpful. I replaced this tonight. I also replaced the sparkplugs about 6 months ago. The check engine light disappeared but came back on after driving. What else could it be? Or do I just need to drive it until the care recognizes the new part?

@acatnamedjoex4688 10 месяцев назад

Could be o2 sensor if you're having the same symptoms

@HomeOwnerRepair 9 месяцев назад

Pull the code to see what the check engine light is pointing to. Sometimes it takes 100 miles of driving or three heat cycles after a repair to clear the code on your vehicle. Hope this helps you out.

Hi, on an '04 4.0 i6 jeep I've got multiple misfiring cylinders 2,3, & 6 with a shaking engine and pulsing power when driving under a load. Upstream o2 sensors have been changed, fuel filter has been changed and plugs have been changed. Is it possible to be a bad coil pack that's causing the multiple cylinders to misfire, and is there any way to test that without a spark plug tester to determine if I'm getting good spark?

@HomeOwnerRepair 6 лет назад

Same thing happened to me. I changed the coil pack and it helped, my crank shaft sensor also went bad and triggered those codes, you may want to try to chand it as well if you keep getting misfire codes

@etherealink09 6 лет назад

So far the coil pack has done the trick, I'm looking at changing the throttle position sensor since I only idle down to about 1k rpm but I'm not in any big hurry until I test it

@angelcortez6007 5 лет назад

I had a REAL HARD time putting the electrical connector back on. It only went on about 98% but not enough to hear a “click”. The Red tab wasn’t able to slide over. I spent over an hour trying to fiddle with it.. I ended up just putting it all back together without sliding the red tab. I don’t know what to do.

@HomeOwnerRepair 9 месяцев назад

That tab locks it in place. Check the plug ends to see if there is something preventing the harness from sliding in all the way.

@Christophersanchez1326 3 года назад

It should clear the check engine light after it started to blink at you! After installing the new coil pack.

I have a question, I followed your video and when I went to start my jeep it was not starting and misfiring. I took the coil pack off and re-installed it and it still did it. Could it be the spark plugs?

Did you gap all of the spark plugs correctly? Is there a check engine light on? If there is you should pull the code to see what it is pointing to.

@@HomeOwnerRepair I gapped the spark plugs, reinstalled them three times along with the coil pack. I’ve taken it all and put it back together several times and it’s just not sparking

good afternoon friend I have a problem with my grand cherokee 99 4.0 6 cylinders the starter coil is broken perp starts and works not 100%, I have put 3 new ones on it and with none it works well it even works worse than with the damaged one, that could be happening? Is it possible that those that I put in despite being new are defective? What I can do?

@HomeOwnerRepair 2 года назад

Did you replace the spark plugs too?

@thadsgudenuff Год назад

The 1999 year require a specific coil pack. The connecting plug is turned different and it affects the firing order. I'd really like to know why jeep did this too!

@angelmedina541 Год назад

How about friend, what faults did you have or why did you change them? I'm interested to know if that's what's happening to mine.

@HomeOwnerRepair 9 месяцев назад

You may get a check engine light with a code that points to a cylinder misfire, one of the things that can trigger this code is a bad igition coil.

@lucaslounsbury8515 8 месяцев назад

to clear the codes undo your battery cables and touch them together for 20 seconds or so , then hook them back up

@HomeOwnerRepair 8 месяцев назад

This will clear the codes is the part that was causing the code has been replaced with a good part. Usually once the damaged part has been replaced the code will typically clear after three heat cycles or around 100 miles of driving. Hope our ignition coil replacement video helped you out.

@adrianzptb 6 лет назад

Help. Jeep wont start after replacing the coil pack. I followed everything on the video and reinstalled my old one and it started. New one wont work but its the right part i got it from autozone
