94 1500 dies when warm
What makes you so quick to point at these two sensors?
I know they were replaced by my buddy but Im not saying they are any good.
OBD1 is not as user friendly as I remember from when I was a kid... in fact, it sucks ***. I remember thinking, "WOW, a computer monitors the engine and can tell me exactly what part is going out. That's amazing, This is gonna change the (racing) world!"
Turns out it did, just not as OBD1....
:)
When we 1st saw it, it gave us fits too.
But we had the equipment to watch the pulses from both sensors and they would be just a smidge out.
The crank and cam sensor would lose sync after the cam sensor would get warm.
Once we figured the problem, it was a few weeks later when Chrysler came down with a TSB addressing the same issue.
Chrysler superseded the P/N shortly afterward.
Later, when I went to work at a outside shop, we tried using aftermarket sensors. They worked great at first, but we found they seldom lasted more than a couple thousand miles.
The typical symptoms were:
Truck starts and runs, from cold fine. About 10-20 mins in, the truck will develop almost a miss. It will act as if timing is out or maybe a fuel issue, but scan tools say otherwise. No MIL set.
Truck cools, starts and runs fine, until it starts all over again.
Always with 94-2002 Chrysler 3.9L, 5.2L and 5.9L Gas engines.
Man, I saw this hundreds of times over the years. Happened to my truck twice.
