Question about 1994 Oldsmobile 88
I was taking my daughter to school and my car shuts off. I pushed it home and the next morning it started back up with no problems I have changed the spark plug, thermostat, and alternator. I do not know what to do next
Sorry I hadn't been on here in a while. Not sure if your stil having trouble with your car. But I had a 94 Olds 88 Royale that would stall out and then immediatly turn over. I replaced the TPS, Throttle Posistion Sensor and there ya go SOLVED!!
I tried lots of stuff first but to no avail. I finally tried that it worked. My car would stall out when I was idleing to a stop and sometimes it would shut off. I took the car to my mechanic and he could not pull a code. So he said it might be the TPS. For some stupid reason I thought to myslef "I'll be its expensive" so I never did anything about it. One day it stalled and that was it I went ot Autozone and got the darn TPS. It was $53 and some change plus tax. I put it in and it never stalled again.
Hope that helps.

First of all don't go looking for a distributor cause that car does not have one. It has a coilpack that is triggered by the ignition module wich sits underneath the coilpack on the front of the engine on the right side with all the plug wires goin to it. mcmuff- this is a D.I.S. system. That means: Distributorless Ignition Sytem.
It is really hard to check the module cause unless you work for the dealer like i did back then, you can't get the test perameters you need. the primary voltage from the module is arround 1100 volts.The secondary voltage from the coil is 30,000 so be carefull!!
My guess is a bad crank sensor wich like mcmuff is thinking , is vonerable to heat soaking like a module or coil in a conventional distributor system. It is not easy to test these either. Its dangerous but the best way of checking the crank sensor is to tap it with a long (24") screwdriver. tap it rapidly but not so hard you move it in it's bracket. If the car stalls or stumbles it is the crank sensor. The crank sensor tells the pcm and module when to fire the injectors and plugs with some help from the cam sensor to synchronize them. The cam sensor WILL NOT make the car stall if it goes bad.
I'll keep an eye out for ya for any more questions if ya need.Good luck........Scott
