I want to give a big thanks to Chuck Tator and the people on this board who helped me with an erratic idle issue. I was getting code 505 (idle system control malfuntion) on a regular basis. Per Chuck, I cleaned the IAC and performed a field ground to the battery, and plugged and unplugged the PCM, all to no avail. Chuck also suggested that the wires from the IAC to the PCM be checked. Being a lazy s.o.b, I performed a quick visual and could not find anything obvious.

At my local dealer, their viper tech stated that the their computer showed that the IAC was bad, it was replaced with a new one, no change. He also had checked the wiring and found nothing wrong. At that point, they called dodge tech assistance who said it must be the PCM. $700 later, problem and code still there.

Frustrated, the tech decided to unwrap the wires to check each one individually. He found that three of the wires going to the IAC were melted together because they were located too close to the headers. After replacing the wires and relocating them away from the headers, the car runs great and the idle is normal with no codes

The dealer would not admit that the original PCM was fine, insisting that it could of had a bad driver. :rolleyes: They spent 8 hours @ $85/hr doing the wire fix so it was a wash as far as the cost. I would rather have a new PCM for the money instead of paying for labor.

So the maral of this story is : had I listened to Chuck in the first place and did a full check of the wires, I would have saved a lot of time , money, and BS. THE WIZARD RULES! :headbang: I will never betray him again! :nono:

Another example of why it makes sense to replace the heatshields after installing headers. I ran for two years without a problem but decided to put the shields back on for peace of mind. I know there are several guys running without, but why take the chance!!:usa:

Dave, the dealer had to send the original PCM back to Dodge for a core. I was told that all PCM's for the older cars are rebuilt.

RTED, I have a set that I will install, thanks for the heads up

That sounds similar to my problem, although mine was wire that "rubbed" into a bolt. Same codes and same symptoms..

P.S. I have a PCM for sale..

I tried to take a picture but there are too many things in the way to see exactly where the problem was.
