Can anyone help me? I can't figure out why I have a Check Engine Light.

:mad: AAARUIUUUUGHH!! :mad:

Heres the thing:

I bought my '98 Z from a whole saler. I knew jack about the car when I got it. I should have never bought the car, as I am now going though and fixing someone elses problems.

Anyways, since day one (about a year ago) I have always had an SES (service engine soon light). I had it checked out and they told me it was because the car had no cats on it, and the O2 sensors weren't reading anything. So, it seemed like a set of O2 simms would fix it....I just never got around to buying them.

Well, this weekend I was installing a Drive Shaft Loop, and decided to take a look at the O2 sensor wires.....and what do we have here? O2 simms. Frickin' A! The guy who owned my car before half-assed everything.......but this was one thing he did right. I wasn't counting on that. So now my easy "SES" light fix doesn't seem so easy.

I would like to see if anyone has an AUTOTAP software to see what is causing the light. If i still reads that its the O2, I can get a new set of the simms.....or figure out what it is really doing. I used to have some GM dealer hook ups (ie free scanning) but since I've moved, I don't have those connections any more. I don't want to have to pay $50 bucks if some one can help me here for the cost of lunch.

So, if anyone has a spare day on the weekend and would like to help me see whats going on with my car...please, please, let me know. I'm so sick of this....


.....and in doing the Drive Shaft Loop, I found a STEEL drive shaft. How awesome is that?? My car is a '98 LS1. Only the LT1's had a steel one. <shakes head>


Again, please let me know.....and I'll cover lunch that day.
I'm in the north Grand Rapids/Comstock Park/Rockford area.

:bow: :bow: :bow: :bow:

Thanks.

Free?? :confused:
If so, I'll give it a shot.
Thanks for the suggestion/idea. :D

I thought you could just take a paper clip and connect two of the pins on the ALDL, thereby causing a light on the dash to blink. Then according to the sequence of blinks you can tell what the problem is. Or is that just on older cars? :confused:

Yeah its free...


pete
havnt been able to do that in like 7 years

Just wondered. I know you can do that on turbo Buicks, but I realize those are "old" now. I have a very limited knowledge of computer-controlled car stuff.

If you cant make it to Autozone, I have an OBD-II scanner for my laptop and the GM cable. Let me know if you need it.

That would be awesome.
I'd rather meet up with a fellow cz28 member, then an AutoZone worker. Maybe I could stop over sometime next weekend? Let me know if this will work for you.

Thanks!

Milo,
I have O2 simms too and every once in a while it will set a code. I go in and clear it and no problem for a while. Like Dave said go to Autozone and have them read then clear the code (if it's the O2s) you may be OK for a while.
As far as the drive shaft goes. In 98 if it was a 2.73 A4 car it got the steel shaft. All sticks and the 3.23 A4 cars got the aluminum one.

Al, thanks for all the info!
I thought it was that ALL LS1 cars got the aluminun drive shaft...guess I was wrong. I'll be calling auto zone soon. If it is the O2's, I'll have them clear it and see what happens.

I do know that when use my HPP......I don't get the check engine light until the computer cycles though a few times. So...who knows....
