Here's what I've got:

1991 Stealth SOHC runs very rough with low loping idle for a minute or two and than stalls out, it may do this a few times than eventually the engine just cranks and no restart. An hour or so later you can repeat the same senerio. Any help is much appreciated.

Thanks

is the MAF plugged in?

 

Yes, this happened a few weeks ago was able to limp the car back home. If you hold it above idle it will run but you can hear it pop in exhaust and smell the rotten egg smell.

 

Then your ecu is most like bad. Leaking capacitor. You need to either get the ecu rebuilt( if it can be), or buy a replacement one.
