A question for those who are mechanically inclined...

My brand new '03 Wrangler is in the shop. I've had it for about 6-7 weeks.

Ever since I got it it has been making a "pinging" noise. (It sounds kinda like a phone or pager vibrating on something metal) I took it to the dealership about a week after I got it and they thought it was "bad gas", and I needed to use the super premium for the next few fill-ups.

Well, it kept doing it, so I took it again a few weeks later and they couldn't hear it (it only had the bikini top on, but I can hear it fine going 70mph down the freeway with the radio blaring!) I think they just saw the bikini top on it and didn't even bother taking it out that day.

So, I go to the trouble of putting the hard top back on
and I took it there on Saturday. The service manager was talking to my step-dad (and not me) and he said that there is something wrong with the distributor.

He isn't sure how to fix it besides re-programming the whole computer and he said that they didn't want to do that. Does anyone know why they wouldn't want to do that?

Has anyone heard of anything similar to this? They haven't called me back today and I am getting impatient. They gave me a '03 Dodge 1/2 ton to drive around until they

Any comments?

WTF?
what dealership is that!

I would bypass the 'service manager' and talk directly to the guy in charge of the service department. - you have to make them fix it or you will live with it for 6 months and then they will tell you its not under warranty because you took it offroading. (they will try this line of BS everytime).

that is insane, I would take it to another dealership after that load of crapola...

I did talk to the guy in charge! That's the bad thing.

My step-dad got pissed (he thought they were taking advantage of his daughter) so he went there in uniform and spoke with the head manager of service.
I am just glad that they gave me a vehicle to drive-at first they told him that I was going to have to get a loaner and pay for it.

Well, they have it and they are keeping it until it is fixed-or else they are giving me a new jeep! (doubtful)
I'm keeping their truck until my baby is fixed.

Oh, it is Cecil Atkission is Burnet, the sales department has been great so far, but this is frustrating. (The salesman is the one who made if possible for me to get a truck-the service manager still wanted me to get a rental.)

What an idiot. If you have a '03 Jeep it can't be the distributor .... they don't have a distributor, none of the Wrangler engines do. That thing on the oil pump shaft (where there used to be a distributor) is a camshaft position sensor (aka a CMP).

The device that times the spark is the Powertrain Control Module (PCM, aka the "engine computer") which produces a spark for each plug after the crankshaft position sensor produces a single pulse for each engine RPM. The 6-cylinder motor has three ignition coils and no distributor - each coil fires once per engine RPM, or 3 cyclinders fire per RPM. The 4-cylinder Jeep motor has a single ignition coil and fires twice per engine RPM, or 2 cylinders per RPM.

If you are getting pinging it is probably not related to gasoline octane - both Wrangler motors will run fine on 85-octane "Regular" grade gas. What has been the culprit on such problems in the past has been the electronic fuel injector timing, also known as the "sync set". This is setup off the CMP I mentioned before, and the dealer has to set it with an electronic tool called a DRB III. The correct setting is as near "0" degrees as possible - but many Jeeps have been delivered from the factory with as much as +12 degrees of sync set. If you can get this set properly the ping should end and you should notice better acceleration as well.

KaiserJeep,
Thank you for the information. It is very helpful.

My patience is wearing and I am about to call them and ask what they are doing.

Maybe you could ask in a straight face what about the blinker fluid?

Cause they are obviously trying to take you for a ride. I'd find a different dealer. This one has no idea what is under the hood of a TJ. No distributor anymore... I think they took those away in '00 or '01.

I think KaiserJeep was referring to '03 Wranglers...

I think they went distributorless in 2001 since the hp/torque numbers changed that year...

Yeah I must have read that wrong, when I read " none of the wrangler engines do" I assumed he meant ALL of the wrangler engines. But re-reading it I see what he meant.

Yes, I did print it out and I sent it to my husband! It is very helpful info!

That would really go along good with they way that they haven't talked to me, only my husband or my step-dad. They'd really think I was just a "dumb blonde girl" then.

Right after I read the responses I called and a guy told me that the pinging is fixed, when I tried to ask any other questions he said he was with a customer and had to call back.....an hour ago!! He still hasn't!

I'll let yall know what they say.

Thanks for all the replies! It is all very good to know.

Okay, finally got a call back!

They did exactly what Kaiser said....

The guy told me that they had to change the synchronization setting that was off. (This was a different guy that I talked to today).
I made sure and asked him in detail, he was jumping around saying it was hard to explain, so I just said to him what Kaiser had wrote and he said, "How did you know that?"

Thanks so much you guys! If yall wouldn't have given me this info I wouldn't have known if they were still pulling one over on me!

Yippee! I get my baby back tomorrow!
