My timing is way off and I am getting conflicting info on how to correct the problem! What is the first and /or best way to test and adjust? I 've been told the only adjustment is to replace the timing belt?????%

You've been getting some bad info. The timing is controlled by the PCM. How do you know it's off?

The car idles very slow and also inconsistently.

I asked if it could be the O2 sensors and was told NO (what then do they do?)

I also asked about turning the distributor for adjustment and was told that that is possible and could be the needed approach with the proper tools.

Obviously I am NOT a mechanic, but trying to learn how to maintain my car properly without getting ripped off.

First off, don't ask those people anything any more about Jeeps.

Are you getting a Check Engine light?

When's the last time the Jeep had a complete tune-up including plugs, wires, cap, and rotor along with a fuel filter and throttle body cleaning?

Step#1) Perform a very thorough cleaning of your throttle body, above and below the butterfly. Pay particular attention to the air passages for the Idle Air Control and the MAP Sensor.

Simplest and easiest thing to do first. I think TJWalker has a nice write-up on it.

OP: Do it yourself and don't invite the guys who have been giving you advice over to help.

Sorry - there is no timing "belt." And timing is controlled by the computer.
Turning the distributor won't help, but it will cause other problems.
Oxygen sensors have a totally different function.

Try cleaning the IAC - Idle Air Control - look it up on here (search) or on the web. it's easy to do.

I suggest getting a factory service manual - a real one, not a parts house home version - they are too generic and often wrong. The real FSM's are on CD on ebay for about $30.

Yes, to the engine light issue... thqt has been off and on for some time now and no one seems to hit the heart of the issue. Can this be a system electrical problem. I am totally frustrated by all the diffferent responses. IR Bag lightg also shows intermittently.
AAAGGGHHHHHHH!!!!!!
