Engine constantly stalls!

  • 1998 CHEVROLET LUMINA

98" Chevy Lumina, 6 cyl, 142,000km
When warmed up car has difficulty accelerating and jerks while accelerating, and then stalls - battery and oil lights on. Any time the car has to "work hard" to accelerate quickly (turn a corner, climb a hill) it seems to stall. At times it also stalls at a dead stop. Takes a few minutes before car re-starts again. Mechanics are stumped! Have no idea what's wrong! Please help!

HAs anything been replaced yet?
HAs the computer been checked for codes, if so list them. IF not, check them.

Ths shop should have a scanner that is capable of taking a snap-shot over the stalling when it happens, the data stream can be anaylzed and combined with the codes, there should be a very good chance of what is happening.

Also you can disconnect the EGR valve connector and drive it to see if the problem stops. Just for testing.
IF you haven't already cleaned the IAC motor, egr valve and passageways, and the throttlebody, these would be recommended.

I have a 95 (3.1L, 140,000) that does essentially the same thing. Does it only do it sometimes? Mine seems to only do it when it feels like it and rarely while I'm driving, only at start up.

Has the fuel pressure been checked? Some of those GM cars had a "pulse Dampener" on the fuel pump that sometimes would let pressure bleed off resulting in poor running and hard starting

Need more info did it crank back up? Check engine light on? Was it low on fuel? With that many miles could be numerous things.

I have a 98 chevy lumina 3.1 and it just had the starter replaced. Now it shuts off while driving it, it will start right back up again but after driving for a little while more it keeps shuting off. Any suggetions on what it might be. I have also just replaced the pvc valve, air cleaner, spark plugs and changed the oil.

Intermittent issues can be hard to track. You have to test when problem is ongoing. Any applicable trouble codes? Some of the national brand autostores used to check codes for free, if there are any.

Does the problem occur going down the road or at idle?

Hi:
Have you had the alt checked? It sounds like there is a problem with the voltage regulator. Most parts stores will do it for free.

Let me know what you find.

Electrical problem
1998 Chevy Lumina 4 cyl Front Wheel Drive Automatic 65,000 miles

My Lumina has had an ongoing intermittent electrical problem for the past year that nobody can find. At time it will not start. When you turn the key it is completely dead except for the doam light being on. It may start the next time you turn the key, or you may have to wait a couple hours to try it again. When you are driving down the road it will start to quit on you. The radio goes out and the dash light start to dim. You can usually keep it going. I have had it in a Chevy garage and they checked the computer and found no error codes. They told me the fuel pump was very good and could find no reason for the failures and could not get it to fail for them after keeping it five days. Could my problem be the ignition switch?

Hi:
Does the security light stay on after the car starts? If so, it will need to go to the dealer for reprograming. I have a feeling the problem lies in the security system. However, not being there with you to see the problem limits me.

Ask the dealer if they feel it may be the problem.

Let me know what they say. I hope this helps.

Engine Mechanical problem
1998 Chevy Lumina 6 cyl Front Wheel Drive Automatic 140000 miles

The car dies often when slowing down to come to a stop. It idles fine. It just seems to shut off. It doesn't sputter or shake, just shuts off. It will start back up perfectly when you try to restart it.

Thanks for the suggestion but I think that we found the problem. Somehow the air intake hose came loose between the throttle body and the air filter. It pulled in some dirt into the throttle body. After a good cleaning it runs great.

Hello there,

For the past 4 days, I have been dealing with my engine randomly stalling & shutting down, usually when I am going at slower speeds or idling while at a light, or just parked. For about the first 10-15 minutes, there will be no problem but as I continue to drive, the car will start to constantly ALMOST stall but manages not to, but when I slow down just enough or am in a state of idle, it will stall & shut down. Usually I can get it to turn back over right away, but there are times where it will automatically stall & shut down again and will have to keep turning it over for at least a minute.

I notice that when the engine stalls & shuts down, three lights in particular turn on. The "Change Oil Soon" light, the "Oil" light & the "Volts" light. However, the car has actually just recently had an oil change, so I do not believe that is the problem.

One light has been on consistently for a while, which is the "Service Engine Soon" light. I have had the car checked out at AutoZone for any codes relating to this light and it is saying it is a code P0401, which relates to the EGR valve. I have since cleaned out the EGR valve & the EGR intake passageway with carb cleaner spray, and managed to get out a lot of gunky buildup. I also took the time to clean the throttle body with the carb cleaner spray & clean the Mass Air Flow sensor with Mass Air Flow sensor spray. This does not seem to have helped in any way, shape or form though.

At this point, I'm not too sure what to do, as I need my car to commute to my work as it is 60 mile commute altogether there & back. If you could help give me some insight, I would greatly appreciate it. Thank you in advance.
