Chevrolet had a problem with it's combination sender/switch units used on the 350ci (5.7L) TBI engines in full-size trucks and cars between 1990 and 2000. The sender becomes inoperable due to a loose wire inside the sender itself and makes the gauge erratic. The fix is to replace the sender/switch.
