    I had a check engine alert light on and the car is going along but every once and a while it just cuts out, as if the fuel was cut off. Red dash lights come on and everything just cuts off. With the check engine light on I got a buddy at a repair shop to hook it up to a scanner. I saw, with my own eyes, EGR Valve & O2 Sensor. The most expensive, the EGR valve was changed first. Now, I don't get a check engine alert, however the car still stalls at irregular times during my drive. Come payday, I'll change the O2 Sensor in about a week. I need this to work, as I am going on a round trip of about 900 miles in September.

    95 LeSabre sometimes runs good, sometimes won't hardly run at all. When turning the ignition to the 'on' position, both fans come on when the engine is stone cold. After starting, will idle erraticly but runs good once you step on the gas. It might run great to the store and back, or just decide to die while driving down the road. I suspect the ECM is fried.

Make sure the battery terminals are tight. These cars have a double stacked positive side terminal that, to get tight enough, usually means stripping the threads on the battery. After fighting with this connection for more than a year, I finally put an old fashioned post adapter on the positive threaded side terminal, then put another 'marine' adapter on the post. After stripping the rubber insulation off the two positive wire's terminals, they'll stack up on the marine post and wing nut them good and tight.

Engine stalls while driving!


as your description is a little uncertain that is why the answer are a little mixed
however the basis of the description indicates a battery problem , probably loose/dirty battery terminals or loose /dirty ground wire to the engine
check the ground wire condition

1993 Buick Century satation wanon sudden stalling.


How long since a tune-up? Any applicable trouble codes? Two things off the top of my head, problem with ignition switch or intermittent rpm signal. I have no way to be sure?
When it stalls, does it quickly restart, if not, do some testing, see what your losing, fuel--spark--whatever.

Engine light flashing


Whens the last time you checked the oil or had it changed, should probably check this first. If it's low add to the line(probably real low) and get the oil changed asap.

I have a 1995 ford f250 with the 7.3L diesel. The vehicle makes a large sucking noise when cold, and the engine loses power. when the rpm's pick up, it regains power and drives well. Problem goes away when...


The problem is due to a lack of compression in the engine when the truck is cold, try using the engine block heater more, or allow more time for the truck to warm up.
