the last thing i did was pull the starter and the wires from battery to starter.i looked at them real close,looking for burns or cracks.they were all in great shape.after putting it back together,for some reason the car wasnt resetting at idle.just at a wot now constantly.so the wire to the ign you are talking about seems like a good idea.without having to look it up in the book,does the wire to the ignition come from the starter?directly to the switch on the column?or fuse block first?
thanks
The fuse links from the starter power the fuse box..ign switch. Follow them they go down the firewall under the wiper motor. I just broke down and bought a new harness for mine for similar issues. I am at a loss I have tried everything.
Check all pins in the module female connector. I've seen intermittent connections cause similar problems. Bend the pins with a small pick for better contact. Id also check the harness for bad splices and tap ins. You may have a short to 12v or a signal wire shorted to ground 5v or 12v. Here's what you see when you start digging:

I been finding allot of corrosion inside the ecms. Mainly the chip sockets but also where the chip sockets are fixed to the board. Don't forget to check the calpak chip as well. Clean off any corrosion and use a little dielectric grease on the chips.

Who knows? A lot of these cars are like that. Sometimes you can spend 5 hours just cleaning up all the bad splices and cut wires.

i sent my computer with chip/powerlogger to eric and he couldnt get it to reset one time.none of my wires are in that shape at all.
their are splices that ive made that im going to have to go over with a fine tooth comb.going to run some temporrary bypasses to find the exact culperit.

I would bet some settings were played with in the Tpro.
When it comes time give me a call. We can go through it.

yesterday i decided to cut off the factory orange plug from the battery to the computer,it feels a bit soft.i used a jumper wire from the top post of my battery.all the sudden it caused it to do that idle rough and die.so today im going to start looking around that area by the relays and map sensor stuff.wish me luck!cross your fingers.it hasnt run like this since the beginning of this issue.
