Default 1989 C4 corvette random stalling...

Hey there, I've been having an issue with my Vette lately...

My car, every couple of days, will randomly stall and give me the SES light. When it starts to stall it has an extremely low hiccuping fluctuating idle for a little bit until it just gives up and dies. It's very strange. The SES light only comes on for the moment it does that and then goes away right after the car is done throwing its fit. Usually the car will return to its normal self right after I restart the car. I'm not understanding what this is :/

I've taken it to a mechanic but of course for the 2 days they had it, it didn't cause any problems so the mechanic is no help at the moment.

If any of you have some sort of an explanation for this freak thing that's happening with my vette, please feel free reply with some answers! Thanks!

You need to pull the error codes to find out what the ECM is trying to tell you by turning on the SES light:

Make sure there are no leaks near the MAF sensor connections.

Your MAF sensor could be on the way out, see if it drives better with the MAF sensor unplugged.
