1996 Dodge Intrepid Acceleration Power Loss Fix

[quote:51c5acd200="skeeter586"]I have a '96 Dodge Intrepid 3.5 w/ `175,000+ miles on it. It was back firing, making clicking sounds, and shaking pretty bad @ about 45mph. Diagnosis was 2 cylinders were Not being fired caused by the computer not reading it. Replaced computer and spark plugs. NOW....problem returned for a brief moment leading to...only 2 cylinders working:( They said it was the Electrical coil shorting out the computer. All cylinders work, but loss of power in acceleration. As of right now....they have no idea what the problem is..... HELP ME!!!!!!!!![/quote:51c5acd200]

So they have replaced the PCM 2 times? When you said electrical coil, are you talking about the Ignition coil? Did they replace it?
I am assuming that you have no engine codes now?

Yes it is the Ignition coil...sorry and yes they did replace it. The codes are all clear. Only 1 PCM has been put in. The ignition coil caused it not to read the cylinders. They reprogrammed the PCM and it works good again.All cylinders are running fine. In idle it sounds and runs fine. as soon as you put it in drive and put some gas, the power goes down and struggles to accelerate.

My gut feeling is that the new PCM is either not set up correctly or bad. If the dealer replaced this and set it up, I would take it back to them and say that new computer is bad.
Be sure to preach to them, when they try and sell u a injector cleaning and tune up, that your car ran great until the computer got fried. They replaced the bad parts and now it needs a tune up? I dont think so.
The only other thing I can think of is that maybe when the computer got fried, it may have messed something else up. But I would think the computer would throw a fault out there if something else was fried.
Good luck and I hope they will fix it for you without a hassle.
