This is what it is in this order
One of your ignition coils are gone. Have them checked
Replace your speed sensor that is on the transmission

    If it's an automatic, sounds like the torque converter solenoid has gone bad. The symptoms are stalling right before you come to a stop after you've been over 40mph or so. To test, simply unplug the blue connector located on the front side of the transmission. If it runs well after being unplugged, have your mechanic replace the solenoid - or you can leave it unplugged.

1989 chevy cavalier z24 strats but stalls rapidly


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

We have a 2006 Chevy Aveo and it is having a problem staying started throughout the day. We try to start it in the mornings and it spits and sputters trying to remain started but eventually stops. Once we...


Start with replacing the fuel filter. The Aveo fuel filter is located passenger-side rear, in front of the rear tire.

If there is no filter there, then the filter is a non serviceable filter and is integrated with the fuel sending unit. Your going to have to replace the fuel sending unit if the fuel pressure is slow, start with running fuel injector cleaner through the fuel system for the next few fill up's and hope that will clear up the issues your having.

The other thing to is that your IAC (idle air control) valve may be dirty and is stuck close, you can try cleaning it by spraying Throttle body cleaner through the throttle body, paying attention to the IAC passageway. A dirty of faulty EGR valve will also do the same thing.

Start with the simple and inspect to see if you do have a external fuel filter, and inspect the wire leads to the IAC, EGR and clean them with throttle body cleaner. Don't forget to run the fuel injector cleaner through your gas tank.

Thank you for using Fixya and good luck.

It is most likely that you have a hole in your vacuum hoses (check your flame trap too) or your 02 sensor is bad. i would check both. good luck:)

My car is stalling when slowing down or coming to a stop. I think it is a vacuum line. HOw can I get a a diagram for a 1989 Honda Civic DX Hatchback 1.5 motor


Your emission system (including vacuum lines) should be on a diagram on the bottom of the hood of your car. If not, leave a comment, and I will investigate further.
Hope this helps.

1989 Z24, 2.8v6 intermittent stalling while driving. Sometimes will restart, but not go far, sometimes will not restart at all. Usually starts fine the next day, may run OK several days before acting up...


the pcm may have a cracked board, i had an 88 cavalier z24 with the same problem, replced the ecu and it ran fine, the problem is that the boards inside the pcm crack and lose connection, the next time it acts up open the glove box and try tapping on the pcm, if the car responds at all, the pcm is bad

Chevy S10 Pick 1995 - Sputters and almost stalls when accelerating.


You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.

1992 chevy corsica runs rough,stall or dies after stopping


Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.
