I'm lost on this one. It just started acting up. I can't drive it anymore because of how it behaves:
Starts cold, fine. I can drive it for 10-15 minutes or so. Then it starts sputtering, which progresses into the engine jerking wildly, the tach jumping all over the place, and it quickly dies.
It won't start back up until I let it cool down.
The only thing I've found so far is that the coil-to-distributor wire measures 10K ohm instead of the less than 2K spec'd in Bentley. If this was a problem, though, the car would have trouble when cold, right?
Weird thing I noticed last time was that after it died and I turned the key back to ON the tach bounced all over for a little while without the engine running. Tach signal comes from coil? Or Hall sensor?
I've checked all grounds, battery, plug wires.
Any suggestions, besides shooting it?
