I'm Having some problems that somebody may be able to help me with. I've got a 93 Z34 that I'm trying to get on the road. My 99 Lumina is rapidly dying of cancer/rust. The rear suspension is pretty much just flopping around,,, NOT good.. I NEED another car,,, quick!!
Back to the 93 Z34. A little history.. The car has been pretty much just sitting for around 10 years. During this time I put in a motor (59,000 miles) and a rebuilt tranmission (4T60E).. Everything was working fine and the car ran great. Along the way water got into the car, probably through the passenger door seal. There was a couple of inches of water on the floor and it has never totally dried out. Don't know if this is contributing to my problems but, felt I should mention it. The car got covered and sat some more..
About two weeks ago I dug the car out and got it running.. After fixing a few small problems, mostly electrical, like turn signals. The car was running pretty good. Last Wed went to DMV (was there 6 hours.. They close at 5. Didn't get out of there till 7:30.. 6 hours!! MY FAVORITE PLACE!!). On Sat I took it to get an alignment. On the way home It got hot, need to track down a small coolant leak. Then it started throwing codes and idling high.. Then the tranny started to slip when taking off from a stop,, pretty sure all the other gears were working... When I checked the ATF it was low, didn't show on the dipstick. 1.5 to 2 qts over filled it somewhat.. The codes I got were: 24--VS Sensor..... 35--Idle speed error..... 53--System Over-Voltage...
At this point I have cleaned the IAC valve,, no change.. Then I replaced it with a new one and reset the IAC (5 seconds key ON---10 seconds key off and then sart the engine,,, no change, although once in awhile it will idle fairly good, not perfect but, OK.. After clearing the codes (pulling ECM fuse under the hood) I still get the 35 and 53 codes. I checked the modulator and the hose was all rotted and disconnected.. Replaced that with a new hose. No 24--Vs Sensor code, but haven't driven it other than backing out of the driveway and putting it in gear,,, still slips... I'm sure that if I drove it the code 24 would get thrown again... Don't want to do that until I get the idle problem sorted out...
So, that's where I'm at right now.. Does anyone think the ECM took a dump?? It seems funny that everything happened at the same time. I can't believe I fried the tranny by being less than 2 qts low. It's only got about 500-1,000 miles on it.. I've read about people with lower levels of ATF bouncing off the rev limiter to get the car moving.. I babied it home.. I don't want to just throw parts at it and hope for a fix.. If I could get the idle under control it might fix the high voltage issue.. The next step would be the TPS, I read that this could effect the VS Sensor and the idle.. Anyone have any suggestions??? I really need to get this fixed ASAPINS (as soon as possible, if not sooner!!), The 99 is NOT safe and I'm in NO mood to die!! NOT YET anyhow!!
That's about all I can think of right now..
ANY suggestions would be VERY welcome!!
ThanxXx,,,
