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.
