Check engine light comes will stall with no warning

I just this car 2 days ago..Drove it home approx. 75 miles.Then took the kids to school ..another 30 miles...get bak into the car and the Service engine soon light comes on.Call and ask if it had done this before and got a "no" answer...Now the car ran fine for about the first 15 miles after the light came on then just quit warning...the only reason I knew it had stalled was the power stearing did't work...I was going about 40 mph at the time...I put thre car in neutral and re-statred it right away and it ran good...The light did not go out....Then later in the day it was doing the same thing and stalled out 3 times in less than a mile...Not sure what it is but I would assume I have to get it checked out soon....

U have a problem in the ignition system, most likely the ignition module or the crank sensor are failing, it will strand you soon and not restart, have it checked ASAP.

I had this same problem, with my 94, I bought it used, with only 38.000, it now has 68.000, I was having the light issue, and nothing was happening, But then I was driving home from work at 2:30 am, and the Car just stopped running, no warning, I coasted to a stop, let the car set for about 3 min, then I restarted the car. drove home. The next day I checked the Fuel pressure,, with fuel pressure Gage.It bogged,after i checked it 3 time, every time it would bogg, "meaning" the gage would twitch,,,"Not stay steady" So I figured it was the Flue pump, or filter. I changed the Fuel pump, Strainer basket, and replaced the fuel filter, and have had NO other problems with the car sense. Fuel pump & strainer Basket are in the Tank,about $150.00. Fual filter $21.00. Is FWD diver side, along the frame rail, before fire wall, below floor board of Driver seat.If you do it your self be sure to depressureize the Flue rail system,on fwd side of intake manifold,, for both application.It took me 3 hrs,,,Good luck.

Check engine light is on

I would disconnect the battery for three minutes and reconnect it. That should remove the code. You will have drive the car up to about 75 miles to see if the code does or does not show up again. It may have been reading the amount of air in the system from removal of the injector.

Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle.
1 run liquid fuel line/injector cleaner in 1 tank
2 check fuel lines for debris
3 change fuel filters
4 have fuel tank flushed
here is trouble shooting order less expense to greater.

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.

Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!
