1998 Z24 Convertible Issues with codes
Wednesday, August 04, 2010 4:19 PM
Ok so I just picked up another Z for DD duties while i work on the 2000z. It has teh following issues and I would appreciate some help in troubleshooting.

The trans feels like it is slipping a bit at speed, nothing bad, but considering the code, maybe a problem with the torque converter locking. The engine has a vibration, but does not feel down on power.
The ABS and airbag lights are both on. I cleared all codes with my dads snap on scanner, so check engine did not come back. I was not able to access the abs functions of scanner, the computer did not connect for some reason.

1. p0113 IAT Curcuit signal high
2. p1629 Theft Fuel enable incorrect/ no signal
3. p0742 TCC circuit stuck on
4. b1024 driver loop short to ground
5. b1018 pass loop short to ground
6. b1071 internal sdm problem
7. z22? history loss of SIR serial data

thanks for the help, I hope there are a few people still here with the bash going on!

teh guy that owned it hacked some electrical from what i can see. i would car fax it, but meh. it looks like the paint was very well blended in that case, i havent seen evidence of it yet.
i see your point, the only thing i can think is see if the wiring is messed up

wow i think a new harness would be a great start if the guy hacked it. Nothing worse then trying to figure out some ones mess.

I think bigfoot is blurry,
that's the problem. It's not the photographer's fault. Bigfoot is blurry. And that's extra
scary to me. There's a large, out-of-focus monster, roaming the countryside.

the engine bay looks pretty good, there is some overspray on the hood bumpers on the rad support, but looks more like a respray versus new parts, I am not sure, the var looks good, drives straight. I drove from ct to nj yest with no problems. the underhood doesnt look bad at all wiring wise, it is mostly the interior like stereo that was hacked up. I rewired the radio today so that should not be an issue. I changed out some fuses as well, we will see. the trans doesn;t feel bad at all i havent stomped on it, there is no reason too. i just think the abs and airbags are weird. I was considering disconnecting battery and testing the circuits, but since this car has a date with destiny next week, I am not too concerned about it.

btw jeffie, can't wait to hear this new exhaust!
