1998 Oldsmobile

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!

Recent repairs:
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.

Could be the CPS again-this time get the Tech to view the live data-maybe its the computer

Is there anything else that could be the culprit, besides the CPS. This will be the third time replacing it. Thanx.

Check the fuel pressure the fuel pump could be failing

Hi! You have my sympathy -- my 1987 Oldsmobile is doing the same thing! Watch for any answers to my questions (" colorado wildflower hoping for advice" ), as these might help you too! I'm wondering if it could be a faulty alternator. Tires Plus put in a new fuel pump (didn't help), new fuel filter (didn't help), new spark plugs (didn't help), and new ignition module (didn't help). So these are things that didn't work! This is dangerous -- if a car dies while you are driving it, you could have an accident. Must be some simple solution, right? If your CPS has had to be replaced 3 times, there must be some other cause for this. Good luck!

My 98 olds. Intrigue started to do related symthoms like the idle drops and goes to normal while I'm driving. A few times it has stalled on me, but it starts with no problem. Not even the CHECK ENGINE LIGHT comes on, so can't pull any codes to trouble shoot it and my mechanic wants me to bring in for a Fee connection. But it runs great after it happens. What did you find with yours? JOE

I had same issue I got test code it came out to be PO401, which is EGR. You may have to change the EGR valve.
