#1082 of 5143 PCM problem?
Apr 12, 2005 (5:48 am)
My 1997 Jeep Grand Cherokee Tsi (5.2L) recently started dumping coolant about as quickly as I could put it in. I looked as best as I could to identify the primary source of the leak and concluded that it was most likely the water pump. I replaced the water pump, all hoses, vacuum lines and started it up. The engine ran great, but the leak was now much worse and could clearly bee seen coming from a ruptured seal to the timing chain cover, right in back of the water pump.
I went back in and replaced the timing chain cover seal but did nothing to the timing chain or distributor. I reassembled everything and went ahead and put on a new cap, rotor and set of plugs. When I tried starting it up it was missing horribly, flashed codes 11 and 12 and kept surging when trying to find the idle. I pulled the distributor and it looked to be aligned fine when at #1 TDC on the compression stroke.
I gave up and took it to a Jeep dealer, giving them this whole story. They claimed it was the Crankshaft sensor so they replaced it and nothing improved. They said it had to be the timing chain or PCM. I got the car back from them and replaced the timing chain -- again no improvement. I have also replaced the Camshaft position sensor and checked all wires to both the Crankshaft position sensor and Camshaft position sensor. Everything checks out fine and the sensors appear to be working fine.
Any ideas?? The car is undriveable because of how rough it runs. When I disconnect the Camshaft position sensor while it is running there is no difference in the rough idle at all -- for what that is worth.

You might want to have the tie rod ends checked also. They make a clunking sound when turning when they start to go bad. If it turns out that that's the problem, you want to have it repaired right away. You don't want to lose your steering while going down the interstate. It should cost about a couple hundred to have fixed.

I BOUGHT A 99 JGC 4 WEEKS AGO AND IT HAS BEEN IN WITH CARMAX. THAT IS WHERE I BOUGHT IT FROM. I HAVE HAD NOTHING BUT PROBLEMS WITH IT SINCE I GOT IT. FIRST IT WAS SWAY BRACING, THEN THE SHOCKS WERE BAD IN THE BACK. NOW THERE IS A NOISE COMING FROM SOMEWHERE ON THE VEHICLE WHEN IT REACHES 40 MPH. CARMAX HAS TOLD ME THAT IT IS JUST TIRE NOISE. I HAVE ASKED 4 DIFFERENT PEOPLE WHAT IT COULD BE AND THEY ALL HAVE SAID THE SAME THING. THEY HAVE SAID THAT IT COULD BE THERE DIFFERENTIAL, OR THE TRANSFER CASE. I HAVE TAKEN TO A MECHANIC AND THEY HAVE TOLD ME THE SAME THING. I TOOK IT BACK TO CARMAX AND THEY WILL NOT FIX IT BECAUSE THEY HAVE TAKEN IT TO A DEALERSHIP THAT THEY DEAL WITH. THE DEALERSHIP HAS SAID THAT THERE IS NOTHING WRONG WITH THE VEHICLE. WHAT SHOULD I DO? SHOULD I TAKE IT TO ANOTHER DEALER AND GET THEM TO LOOK AT IT? IF THERE IS SOMETHING WRONG WITH IT SHOULD I GET CARMAX TO PAY FOR IT TO GET FIXED? DO I HAVE ANY LEGAL OPTIONS THAT I CAN PRESS ONTO CARMAX IF THERE IS SOMETHING WRONG WITH MY VEHICLE? SOMEONE LET ME KNOW AS SOON AS POSSIBLE

Sounds like it to me. I felt it clunk in the steering wheel and right under my feet. The side that broke was on the driver's side. But sometimes it was hard to tell which side the noise was coming from. I would definitely check the sway bars. If you are mechanically inclined, they aren't in a difficult place to get to. But a shop could fix it fairly quickly.

I bought a 99 JGC 4 weeks ago and it has been with CARMAX for 2 of the weeks. That is where I bought it from. I have had nothing but problems with it since i purchased it. First it was the sway bracing, Then the shocks in the back were bad. Now there is a humming/ winding noise coming from somewhere on the vehicle. CARMAX told me that it was only tire noise. I have asked 4 different people what it could be and they have all told me the same thing.They have said that it could be the differential of the transfer case.I have taken it to a mechanic and they have told me the same thing. I have it in writing form the mechanic. I took it back to CARMAX and they will not fix it because they didn't believe that there was anything wrong with it, so they took it to the dealership that they deal with for JEEPS.The dealership says that there is nothing wrong with the vehicle. What should i do?Should i take it to another dealership that i have talken to and get them to take a look at it?If there is something wrong with it should i get CARMAX to foot the bill?Do I have any legal grounds on this situation if there is somthing wrong with my JEEP?Some let me know as soon as possible.

I wrote this earlier and I have to apologize, I did use one profane word (because I am frustrated with this jeep)- sorry about that. Here is the revised post.
Here is what I have to say about their pitch RE: warning lights- IE: Check engine light- baloney... cant alway rely on that, because it does not always come on if there is a problem! That is exactly what they told me, well if you your check engine light isn't on, then the vehichle is running fine... yeah right- 2 days later, NOT, it was stuck in reverse. I have had it in numerous times, but at least 2 times the check engine light was not on, and it was a major prob, and the check engine light SHOULD have been on. The problem is they depend too much on the jeeps' sensors and. those go bad just as often. Not to mention the computer does not always pick up the problem either, but I was told there is a hand held computer they can use while road testing it- hopefully we can try that next. If you have had your jeep in 3 times for the same problem, then check your states lemon law, especially if the one of the 3 trips occurred within the first 12,000 miles or one year which ever comes first. But, lemon laws differ for each state, California has great lemon law protection for the consumer. I now have a lawyer and he has filed suit. I didnt pay for a used, problematic vehichle- which by the way I bought it new, and these SUV's are not cheap. You sure have lived in a lot of places- I have relatives in Phoenix. Good luck w/your jeep!
#1089 of 5143 Not downshiting and hissing/spinning noise in neutral
Apr 12, 2005 (12:35 pm)
I have to bring my jeep back in on Thurs of this week. Would anyone have any suggestions and/or ideas why my jeep will not downshift while going up hills? It used to have great power on hills, but now when I am traveling at 45mph for ex. if I try to increase my speed and have the pedal all the way to the floor it wont go any faster and loses a bit of speed. (This is not consistant). Also, when I put the jeep in neutral while stopped- I hear a loud hissing/spinning noise? Once again not consistant. Would love some feedback, thanks!!! Oh and there is a clunking noise when it goes into reverse as well. This is a 2003 JGC Laredo with 28,000 miles. Tranny has already been partially rebuilt at 26,500 miles. Could my engine be misfiring or having probs?

Hi, I bought a brand new 04 JGC in the fall of 03. It made a whining noise from the start. The head mechanic at the dealership told me they all made that noise. (should've asked to hear others on the lot) A year later we were having the power steering pump replaced. (under warranty) Never liked how it sounded when going into overdrive when accelerating, like passing someone, cruise control up hill, etc. NOW at 25,000 miles, it shudders real bad when you slow down to brake, and then when you finally come to a stop. I believe it is the ABS. So I am disappointed in my first new vehicle in many years. Oh, there is a place on the hood where the paint is peeling off.

Sorry to hear you have had problems already with your 2004- but it doesn't surprise me unfortunately. Just curious, what does your jeep do when you climb hills, does it kick real hard (like a punching feeling) to pick up speed? Thats what mine has done and not sure why- they told me it was normal, but that cant be good for the tranny and/or engine? Sounds like your rotors might be bad, which is very common with the jeeps.
