ETC problems, need a new PCM?
First off: 2007 Jeep Compass. 2wd, 2.4L. 104K
About 2 months ago, the day after about an 800 mile road trip, my ETC light came on as I was leaving my driveway. Complete loss of power and could not accelerate past 20 mph. I turned the car off, let it sit for a mintue and restarted and everything was fine. I attributed the issue to the long road trip and didnt pay it much mind.
About 2 weeks ago, upon starting the Compass, the ETC light would flicker and be gone and everything drove just fine. I had the codes pulled just to get an idea of what might be going on and the code came bacl "running too rich" (dont know the code number, just what the guy told me) At this point I had the computer "flashed" and the car ran great after that.
Then, just yesterday while I am driving with my 6 month old daughter, the Compass completely gives out on the road. ETC light on, flashing ESP light on. NO acceleration, and when I came to a stop, the engine was running so rough it felt like it was going to die. I turned the car off, restarted it and same thing happens. Luckily I made it home and decided to have car towed as it was pretty much undrivable.
Mechanic could not find the issue for the longest time. First the changed the spark plugs (as one was loose) and that has not fixed the issue. Now they tell me I need a NEW pcm, with parts and labor will run me $850. I called my dealership and they can do the same procedure for almost half the cost. SO needless to say, I need to shop around here.
After all this, my question is: what the heck can I do about this ETC? Just reading on this forum it seems like the kiss of death. Do I really need a new PCM or just a software update? Any feedback is much appreciated and I can give you more of the car's symptoms if you need.
