You're lucky it still runs , its 20+ years old . there's a ton of maintenance that has to be done I imagine .

By your description, sounds like your running lean on fuel. They changing oxygen sensors, spark plugs, and spark plug coils, See if that works. Best thing to do though is first go to AutoZone tell them to check engine light. They will tell you where to start. It is free of charge.
