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.

I have an 88 Cadillac Deville. 2 months ago I had a new fuel pump put in. It's making a whining noise and the car keeps dying and sputtering. What else could be the problem to make the pump go out?

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

Yes, most likely a fault in the auto transmission, and the car has shut itself off to prevent further damage.

2003 Cad Deville, while driving engine stopped. put car in neutral turned switch and it started right up, this is twice this happened, 46,000 miles on car.

Hello,Your car probably has the 4.6 northstar engine.This (phantom stall) condition is usally caused by 1 or both of the Crankshaft position sensors.I have seen this condition quite frequently on your perticular car.I would replace both of the crank sensors and that should do the might want to take it to a repair shop due the location of the sensors (front lower part of engine near oil filter) Good luck.

My 2003 ford focus SE shuts off when i come to a complete stop. It does not have a rough idle and it does not do it everytime.

Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Service engine soon light came on and stays on

The warranty company was able to find a used transmission for $900 which was still under warranty and it will cost 11.5 hours for the install, plus shop supplies and diagnostic. Total cost about $2000. I drove the car for probably at least 10,000 miles and it was leaking a small amount of transmission fluid even after I fixed a seal (waste of money) before getting it fixed. I didn't see the fluid though on my garage floor though as there is something that would catch it.

Cadillac dealer stated this is a known problem with the clutch assembly and that there is a bulletin out on it. The reason the car stalls is due to the transmission not the engine. When the car is at a light or the like there is apparently too much strain from the tranny and it stalls the engine. My car didn't get that far, but after reading a bunch of stuff and looking up the codes it appears to be the case. Of course you could get lucky and the solenoid is just bad, probably not though due to the bulletin.

You can read the codes and clear the codes easy enough. If you don't know how there are many posts on the net.

Service engine light comes on at 54000 miles

Replace the fuel filter. The new gasolines with ethanol tend to lloosen any crud in the gas tank, which then plugs the filter. When the engine stalls, the crud falls away, and it will run again until it plugs up again.
