Man that's a bummer!

Have you tried wrecking yards? carparts.com may offer you something.

I had to go through several when I did my v8 swap and the final product came from a junk yard.

We feel your pain! :sad: I'm sure we've all experienced a similar frustration in some form or another.

I feel exactly the same way. Unless one has been there one cannot truly know the frustration a jeep can provide !!!!!! I think it is the perfect definition of masochism.
 
Can this Jeep PCM problem get worse, Yes it can and it has.

Took the Jeep into the dealer and the nice service guy that got me to bring in the Jeep had down cast eyes and didn't want to talk to me and I was sent down to another service guy. He listen to me but made little connection to situation and history of the Jeep problem. He just wanted me to leave the Jeep and go. I didn't know then but I was being manipulated and set up.

Today, this second service guy called me after the shop analysis and said he recommended all O2 sensors be replaced... to start.

But wait, I wanted to know "what if's" and discuss the PCM as possibly being bad and their shops responsibility and promised guarantee since I just paid for analysis, a new PCM, all costing $1250.00 and promised this would fix it.

Which BTW I fully discussed with the first service man before any work was done and I was assured their shop knew what to do and would back up their work. How wrong, it appears, I was in believing him.

The discussion went on with the second service guy until I realized he was the guy that people are sent to when the dealers repairs don't fix the problem. He is the stone wall! Essentially he told me I was going to pay for all parts and time regardless of the situation. He also said if the PCM they put in was bad it was shorted out by my Jeep after I picked it up.

Holy ripoff, I'm so pissed.

He said if I didn't like what he was telling me I could come and pick up the Jeep and go away:( I still insisted on fair treatment and he then said I should talk to the service manage but read reviews about him and he was discribed as another real jerk.

So here I go again. Jeep is throwing the check engine light and can't get it to pass smog. Now I have to deal with another outfit that apparently can't analyze a problem and fix a problem but resorts to changing out parts until it is fixed with the cost going to the consumer... me:(

Where is the quality, honesty and just plain moral decency? So far it isn't at this Dealer, Carson Dodge Chrysler Jeep.

I'm not done. I am going to drive down tomorrow, over 60 miles one way and talk with the service manager and also make an appointment with the owner. Such a bummer, again. Just tire of this.

Another note... owner is lost in a corporation. Found the president but searching only found a front company with no address. Man am I screwed:(
I dealt with these people a while back. Right rear axle seal was leaking and they replaced it. That was fine but then they charged me for pulling the rear diff so they could remove the axle c-clip. Ya it was a Rubicon with D44. It took forever to get my money back. I sure as hell would not go there again!
:mad:
 
OP update: Dealer shop called and left message late Friday, back to the nice guy now. No info about the PCM work, something else!

Oil pump drive assembly is making noise and mechanic recommends to replace unit. Didn't get price but Quadratec has the part for $109.00. UTube has several good videos on replacing so I will do it myself.

Lots of info about this on forums and looks like another Chrysler Jeep reputation problem. You guys probably know all about and I'm just saying what I found for my own knowledge and maybe others like myself. Here is the quick story about the OPDA Oil Pump Drive Assembly.

Chrysler Jeep manufacture installed faulty OPDA's in 05-06 Jeeps with an S in the vin at the eighth letter. I'm so lucky, that is my Jeep. This is an external oil pump the rides on the cam gear, failure may cause damage to the cam and engine will stop. Note: this problem may occur in any 4.0 Jeep engines.

Chrysler Jeep knew this and sent a letter to the dealers "suggesting" all Jeeps in their inventory have the OPDA replace before selling. The big problem is no recall and no requirement to change. Why would a manufacture not want all Jeeps fixed when their assembly line put in faulty parts that can cause catastrophic engine failure? Why not have all previously sold Jeeps called to the dealer for replacement? Money before honor, seems to be low down behavior to me.

Anyway I like my Jeep but think badly about Chrysler/Jeep as a company and wondering what next?

Sorry, but this is such an old issue with the 05/06 jeeps as to be boring. Not you, the info. Do a OPDA search and you will get a flood of info. BTW, I went thru 3 of the bas%^*\s before going GM.
Piece of sh*t design that needs a class action lawsuit!

:p
 
My concern is the service guy said the mechanic didn't want to drive the Jeep fearing the pump might fail!

Previously I never heard the pump making noise but didn't know of the pumps reputation either.

If I don't hear any odd pump noise I will drive it around awhile.

Sorry,
but that is the lamest GD excuse I have ever heard.
 
Frank and Steve,
Your advice makes good sense. I'll call the dealer tomorrow and head on down.
Although got to say, going to the dealer is like going to get your teeth pulled.
Thanks partners
You are welcome. I feel for folks that have Richard heads for dealers. The guys I had in Sandy, UT. In fact I still call Mike and order parts from him for delivery.:p

Edit: They dealer I had in Utah was great to me. I give them a lot of business and they give me enough of a discount to make it a win-win. I make is a habit of trying to be loyal to a company because for me I has really paid off in the long run.
 
:banghead::banghead::banghead:

Your rig is haunted!

Trade: you take my brakes and I'll take your engine. I know how to solve that engine problem!:evilbat:
 
had the 4 bad O2 codes - resolved. - 2006 wrangler unlimited rubicon with 4 liter 6 cyl
first weird thing is my jeep has only 2 sensors, not 4. So I immediately suspected things other than the sensors.
checked wiring for shorts or melting from exhaust, no probs
checked for clooged cat - showed no signs so told myself thats not it
looked for bad fuse or relay, even moved ADC relay into horn position and tested fine
wanted to check everything before contemplating re-soldering the PCM connectors - was not looking forward to trying that unless last ditch effort
noticed that the cable connection closest to driver side slid in and out with ease, the other 2 were very difficult to remove. McGiver'd a solution to press on all 3 connectors - no code for 70 miles so far
A guy has to do what a guy has to do.>:)

I would take it a step further and use a block that only presses on one connector at a time. Just because it looks like the obvious solution doesn't necessarily mean it is.
Good luck
