Troubles with OBD II - HURRY

If you are reading a straight open that is all you need regardless of what a particular resistance reading is on other wires. Could it be just a plug, change the plugs.

Your test is fine Jeff, I'd suspect a connector has come off where it connects to the carbon fiber conductor. I'd install another set of OE plug wires, most wires sold by Autozone etc. are pretty crappy quality. Especially avoid those advertising "low resistance" which will introduce electrical noise into your CB and AM radio.

Plugs are OK, I think. My brother in law replaced them two weeks ago because the engine was miss firing. The boneheads at AutoZone told him that if the Check light was off, there were no codes to gather, so we couldn't see if we were even working on the right stuff.

I'm off to the store to get a new set of wires. This is one of those projects where the expensive ones are the right ones, isn't it?

Hey Jerry, send me your phone number to jstrickland at ez2 dot net.

Over all the years I have been buying wires, the OEM ones from the dealer are the best in my opinion.

I am running them on both of my Jeeps.

Hey Mikes back....

Tell us of your adventures Mike!!! lol

The trouble is, the dealership is closed and it's my friend's car stuck in my garage. I bought some silicon wires that are pretty nearly the same diameter as the factory wires, and they solved the trouble and they have a life time warranty.

I have to agree that this is one of the few places where it pays to buy parts at the dealership though.

My wife and I have had a few 'adventures' lately, that's for sure.... :-)

It's fixed. Sorta. I bought a set of wires from AutoZone because the dealership is closed by now. The problem is solved and the code reader reset the code and it didn't come back. The resistance of the new wires was considerably more uniform than in the old wires. I don't know if this is because the old wires are made to a different standard, or they were close to failure among the entire set.

Thanks. I installed new wires - three days ago - and the motor runs like new.
