As I said, the plugs have been replaced 4 times. O2 sensor no, but
that's been tested several times.

There have been 3 master mechanics working on this issue. It is
currently in the hands of a master tech who specializes in electrical
problems and trains techs across the country in troubleshooting.

As I stated, the PCM has been replaced already (once). That resolved
the check engine light.

Again, it's been in the hands of three (maybe more) master techs,
including one who is a master with the MDS. That was a specific
request made to Crysler.

>1) Take it to somebody who knows what he's doing.

Been there, doing that... at least the best I am told is around here.

Again, the plugs have been replaced four times now and the ground
checked more than you have fingers and toes. Also, the PCM has already
been replaced once along with the coil. No change.

I'm not paying for any more replacement parts until the master
technician can tell me for certain what is the problem.

Yeah, sounds right to me. I've seen how the sensors attach and found
the suggestion hard to believe, but it cannot hurt to check and ask if
anyone has heard of or run into such a problem.

Sorry about the wording. Spacer, shim, whatever. It's a small piece of
paper-like material they use just to install the CPS.

I didn't know there were different ones either, but the two mechanics
currently working on it showed me the difference and the one I have. I
really wish I had the other one.

I still want to know how one mechanic can say the CPS is bad and the
other says it is fine... and they are both using the same diagnostic
tools to test them. I am downright suspicious of all dealership
mechanics (past bad experiences at dealerships) that he really is just
surmising that is the problem from experience, but /shrug. It's been
replaced once already. I would think master techs know how to put one
in and not damamge it (or anything else).

Truthfully, right now I really don't care about anything except
someone fixing it. I've already reached my limit on patience with the
pointing fingers and no resolution. Either I get it back working the
end of this month, or the insurance company of the guy who hit me is
going to have to replace it. Otherwise I am starting by camping out on
the insurance co's front lawn with nasty signs and going from there.
