2003 Cadillac Deville stalls while driving

The engine on my 2003 Deville just shuts off while I'm driving. I just bought the car and This has already happened twice. I was driving about 30mph at the time. Could it be fuel related? I have been using regular gas. The manual says 87 octane is ok. What causes this?

    After a few times after stalling, the engine light came on. I took it to my mechanic who said it was the crankshaft sensor but that he needed a special tool to change it. Only the dealer had the tool. When i tried to have the dealer change the sensor they said they would have to do the diagnostic test themselves and that since my mechanic had reset the light, I would now have to wait until the light would come on again. I don't know when that will happen. Is there a way to change this sensor before the light comes on and inexpensively. I get the feeling this will eventually run into a lot of money.

I would start with replacing the fuel filter. it's the cheapest fix and sounds like the problem.

How can I reset my 2003 deville auto theft


Depends on what set it in the first place. With the doors shut, pressing the remote unlock button twice should disarm it. If not, there is a problem with the theft deterrent system and may need to be reset by a dealer.

1992 Cadillac Deville ideals really slow and miss's when I step on the throttle


Do this frist and then if the miss is still there have the spark plugs and plug wires replaced.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

After a half hour drive my car shuts down turns right back one ,,but will keep shutting off, feels like its not getting gas, already change the fuel filter check the fuel pump presure is fine whats next


Possibly the coil module under the coil packs gets hot and shorts out because it's on the engine, ( dumb design). I have seen that happen many of times.

Engine will just shut down while driving


if it dies on you again, unplug the MAP sensor and plug it back in and see if it starts. If it starts then the MAP sensor needs to be replaced.
