1998 Oldsmobile Intrigue, V6 3.8L, Automatic Transmission, 185,000 miles.
I'm having a problem where my car just shuts off on me while driving or sometimes simply while idling. I was driving to work and the car all of a sudden just stalled in the middle of the highway. It started back up with no problem. Then a week later, it did it again, but this time it wouldn't start back up, therefore I had to have the car towed.
I had this same problem about a 2 years ago for the first time, and took it to a mechanic who diagnosed it as a bad Crank Position Sensor. So he replaced it, and the car seemed to be fixed. No problems for about another year. Then, same symptoms, and same problem according to another different mechanic. This other mechanic went ahead and also changed the crank position sensor. Again car ran fine for some time, until just recently as I explained above, same problem, same symptoms.
Now, my question is, can it be the sensor going bad so many times? Because it seemed to work for a while, after the repair was done.
Another thing is, I noticed that the RPM gauge needle randomly goes crazy, it goes from 1K to 5K RPM's all on its own, without me stepping on the gas.
I really want to get to the bottom of this problem, any suggestions will be greatly appreciated. Thank you!
New ICM (ignition control module), new spark plugs, new spark plug wires, new ignition coils, new fuel filter, new fuel pressure regulator, new PCV valve,
new wiring harness (from ICM to Crank position sensor and camshaft position sensor), new idle air control valve.
