93 sc300 rough idle and backfiring at idle
recently bought a 93 sc300 and it has a rough idle, some vacuum lines were capped with screws so i removed those and properly capped them but it had no change to the idle i have new spark plugs waiting to go in just need to make time to do so also when i turn on the ac it slightly normalizes the surge of the idle and keeps it around 1k rpms pls help
