I know that the ezl module controls the advanceing and retarding of the ignition not able to adjust the timing

I just need to know where it is so I can take a look at it. Thanks!

It will not test for emission it says not ready

Nothing will come on an will not shift in any gears head lights only comes on ! What is wrong??? What can I do to fix this problem

When the back climate control is on the fan does not turn on, no air comes out. It was working perfect,one day it just stopped.

cel on - code po456- I have the pump
just want to know where it is go I can replace it.

Also sometimes when putting gear to drive I get a little stall/bump on reverse

Are the engines the Same from 97-08 on the 4.2's minus the intakes? I need to replace mine 97's 4.2

If you drive the car for a while and park it it may not crank. If we disconnect the battery and wait a while the car will crank. The check engine light may or may not be own.I've had it on the machine to test but they never find anything. I was told it may be the computer.

Washer also doesn't work. What else could be wrong?

the mechanic says he doesn't know whats wrong with it, its getting fuel just wont start.

I tried to start my car and the steering wheel, won't turn, it's not stuck, I can move it left to right, but only2 inches, for both sides, and my emergency brake light and battery light, are not turning off after ignition.

hard to start when cold ok when car warms up

I have new vaccum hoses exhaust tight. Once a day out of nowhere idles rough on start up no telln when it will happen. P0171 code keeps coming back

I started my car (after buying a new battery last week that was larger than the factory one I had) and suddenly my heater is on high and cannot be adjusted or turned off & my radio won't turn on?
It took the mechanic 4 hrs to find it's a sensor in the middle panel (and now can't find the part and said it may need to be built at the factory) so my questions are:
- Does 4 hrs to find the problem seem like a long time?
- Should the part be so hard to replace?
- Could the stronger battery be to blame?
This is a new mechanic for me (I just moved to town) and I'm starting to doubt that I should have trusted my brothers referral.
Thanks in advance for your help. Judi
