Re: 2005 Cherokee Misfire and using coolant??

NO NO NO NO NO NO... it is NOT the PCM... holy hell it amazes me how quickly SOME aftermarket shops land on "it must be a pcm". A coworker just replaced one on a mini van towed in this saturday, the customer payed for a tow, told us to replace the pcm as another shop had already diagnosed it. So my coworker replaced the pcm and retested, same problem... it was a wiring harness that had been sitting on the exhaust and melted through a bunch of wires. Even worse is it happens pretty regularly on these vans and it is not uncommon to get these vans from other shops after having a bunch of sensors replaced and used pcm's installed.

Have they done any mechanical tests? compression, leakdown? Also, there is no stateside 2005 cherokee so are you export, or is it a grand cherokee?

Re: 2005 Cherokee Misfire and using coolant??

Yes it is a Grand Cherokee, been in and out of the shop for the last few months Im not sure what all tests they have done. I tried to call another jeep dealership a couple hours away to see if they had ever experience this problem and they really didnt want to give me the time of day. He says well to me it sounds like a burnt valve but i really cant say that without seeing the vehicle. We I dont have the option to drive that far to get them to look at it and no one in our area seems to impressed with the local dealership. This is my daily driver and I have really got to figure out what is wrong with this thing!! I appreciate all suggestions!

What motor do you have?

Combine with the overheat, I would REALLY lean towards a blown head gasket.

Re: 2005 Cherokee Misfire and using coolant??

3.7l v6, took it back to shop fri and said my heater core needed flushed so he did and now it doesn't run hot,.also said he would need to do it again. I can only hope that some build up was blocking that cylinder causing it to have tooo much heat. Shop really didnt think the head gasket was blown.

Re: 2005 Cherokee Misfire and using coolant??

Find another shop... PERIOD

misfires on the 3.7 are common, and they are NOT repaired by replacing parts or flushing a heater core. a heater core is NOT used in engine temperature control at all unless there is another problem and then you can use it for additional heat removal from the cooling system but flushing the heater core further idicates their lack of ability to fix your car.

Most commonly your looking at a a valve problem. honestly most of the guy at work replace cylinder heads to repair.

Re: 2005 Cherokee Misfire and using coolant??

Been 4 weeks since the shop flushed the heater core and I DO BELIEVE this was the problem, at the time when he flushed it, my heater wouldnt flip over in the mornings and since then everything is running fine!! Gonna take it back so he can flush it again! I think maybe the heater core was air locked and holding all the heat in the #6 cyl.

Re: 2005 Cherokee Misfire and using coolant??

Yes, that is not possible, it is not that sensitive to heat, period.

Glad its not currently giving you problems, I can assure you unless they changed or fixed something VERY stupid like an obviously chaffed wire that they missed previously and didnt have the heart to tell you that all the money you spent was for the wrong repairs and just fixed and never told you, the problem is still there, whatever was causing the problem is going to be back eventually.

^this! That can not possibly fix your problem because the two are not related at all!
