Jerk? That pains me. I kid, I kid. I hope you sort the Jeep out.

 

Hmmmm. Not really useful, so now it's time to do some noggin-pokin'. By that I mean, get your head under there and look things over. Sometimes things are obvious.

How are your plugs? Since you have the coil packs, how is the wiring going to the packs? I'd start there. If the misfires stay with the same cylinders (doesn't sound like it) I'd swap some packs around. This is why it's nice ot have your own reader - you can take multiple readings at different times and see what changes.

Also, how's the fuel pressure? You can rent a gauge at the above-mentioned stores. Basically, you buy it, use it, and return for a full refund. It's a very helpful program.

 

Yes, those were the codes. And I know we was test driving again because we put new plugs and some injector cleaner and it still had a horrible miss with no power at all

 

Yes those were the codes. We put new plugs in it and some injector cleaner. We was test driving it and that didn't help anything it still has a horrible miss and no power at all.

 

I know, I'm sorry I shouldn't have said that. I was just getting aggravated because I had posted this thread for help and everyone was just making jokes besides one person. Your joke really was funny I was just mad. I'm sorry.

 

Ok, we put knew plugs in it, the Champions. And we had looked at the coil packs and I think one of the boots that the wires go in were broke, so we may need one of them. And I also figured out that cylinder 5 was not getting gas, how do you fix that? And then the wires for the coil was broke for cylinder 6 so I couldn't check if it was getting fire.

 

Eventually your time will be worth more than spending an hour to save $15, each time you need one.
Do yourself a favor and buy a code reader. You can't play this game without tools.

 

Go on YouTube. ..
Check out...
"Testing fuel injectors fast"
Then he also has a link to test resistance.
Start eliminating issues.
Hope it's not a piston or valve.
These can be ruled out and checked by checking the cylinder pressures. You can rent a set of gages at auto zone. Easy with a friend. Easy even by yourself.

That way you can rule out the wires to the injector. The piston. The spark plugs. Let us know your results. Do it quick before you build up carbon in the cylinder that's not working. If you do, you'll need a new motor, when you could have just spent one day testing and maybe just fixing a wire or changing an injector...

Well my boyfriend works at AutoZone but I say we will still invest in one

 

Ok, we will check out that video tomorrow, and yes I hope it's nothing motor wise which I don't think it is, and we're supposed to get a compression tester tomorrow to check all the cylinders. And I will if we ever get it figured out, thank you!

 

No sweat. Welcome to the forum.

 

Lol thank you, I know I'll have plenty more whenever we get the miss figured out

 

Ok, we put an ignition coil pack plug in it and that fixed the miss at low rpms and it still misses after a heavy load, the CEL starts flashing and it loses its power. I did notice that you can not go over 3k rpms, it starts bouncing off of the rev limiter, this is under normal driving conditions. What would cause it to go into limp mode after you put it under a heavy load?

 

Ok, we figured out the problem it needed the coil pack and that fixed everything. Thank you guys for your time and help
