'91 Olds 88 will shut down after about 25, 30 minutes of driving. On short trips (under 25 min.) it won't start untill it cools off (about 20, 25 min).
I have replaced the coil and module under it. The module was all melted inside, not burned, just melted, whatever that plastic like stuff is. Also replaced the temp. sensor to the computer. I've been told the next possibilities would be the crankshaft sensor, or the camshaft sensor, with the crankshaft sensor being the most likely, and hardest to change. Any with an idea...?
The only code I get is 43, knock sensor. I don't see how that might cause this though.
