I think I have a vacuum leak. My idle is between 1100 and 1200 rpms. Desired idle says 900rpms. Also sometimes the car wants to idle at 2000 rpms. IAC position is 0. Picked up one of the last set of energy suspension control arm bushings Part number 3.3154G. They discontinued all 2nd gen parts. Also picked up an oil filter housing gasket from GM part number 12337894. Has anyone added the low Check oil and oil pressure light? It would be nice to have both with the gauge. That is how my fiero is. It has an idiot light for both oil and temp along with the gauges.
