My truck last night started spitting and spudering like it was going to die while I was driving, then the power felt really weak. And the faster I went the worse it got so I pulled over. What could it be, recently (Sep) I had my truck in the shop. They changed the fuel pump, fuel filter, oil filter, oil, and checked everthing out and said everything looked fine, now this has happened. I have a Chevy s10 - '94 - Vortex V6 - with 230,000 miles.

Also check the vacuum hose going to the map sensor as they get soft andsuck together making your map think things are screwy. Also check the gasket uner the TBI unit as they tend to blow out and cause vacuum leaks.
