Stuck on the side of the road, again.

[thewoodieb]

Yesterday, after I stopped for food and was sitting in traffic. I've been having a tps sensor signal voltage low problem. It has been causing a power loss, but intermittently would get peppy again after a key cycle. So I decided to check code flashes with the car running, bad idea. The idle went monotone, got choppy and cut off in the middle of traffic. something happend when I put the code key in and I'm not sure what. I haven't bench tested the ECM yet, but I'm currently on the side of the road. Once the car cools down it runs fine again. A shot in the dark: I think I shorted my icm. It ran fine in the morning, but once it gets hot: 90deg, it wants to cut off after about 20 minutes of driving. Can anyone supply me with a ECM pinout chart and an icm pinout chart as well as values? Thanks!

Ignition module...

Let the car sit and cool down under the hood and it'll start up again. Let the sun go down and you might make it home, but I wouldn't take the car out again especially in the heat until you replace it...

Coil & or module. Check to see if there is Goo when you separate them?

I had a MAF sensor that went bad when it got hot. BUT the ignition module/coil pack is a more likely to be the source of your problem(s).
