Chevy issues

Asked by Thomas Jul 24, 2018 at 11:50 PM about the 1993 Chevrolet C/K 1500 Silverado Extended Cab 4WD

Question type: Maintenance & Repair

Okay so I guess my next question would be what the hell is
wrong with this thing when she's at idle her RPMs AR 450
to 500 when you shift into drive they dropped even lower
anytime I come to a stop at a light my oil pressure will drop
to zero so tasteful install and it drinks more gas than a fish
and I have replaced a number of things on this already

Coolant temperature sensor may help with fuel economy. Low rpms could be caused by a faulty Idle Air Control valve, TPS or a leaky EGR. Id start with the IAC as its the most likely suspect and probably the cheapest of the three

The oil pressure light most likely comes on because the rpms are so low that the pump isn't spinning fast enough to create the proper pressure btw so I wouldn't go changing anything for it until you've sorted out the idle issue
