WHAT CAN CAUSE A TRUCK TO RUN ROUGH WHEN IN GEAR AND IDLE?

1999 Chevrolet Tahoe • 281,000 miles

The trucks rpm jumps and oil pressure goes up and down and truck jerks while waiting at a light or stop sign. Sometimes it sounds like it is about to stall too.

Check the oil pressure with a mechanical gauge-if okay replace the oil pressure switch
