Question about 1993 Saturn SL2
My 1999 saturn sl1 began to idle very rough and when i checked for the error from the check engine light it came up as a problem with the idle air control valve. i bought a new valve installed it. still the engine idles roughly, though not as bad as before the engine seems to drop rpms and shake when idling. what else might i be able to do to fix this problem?
A pit\ston might not be working properly

Replace the temperature sensor $15.00 auto zone
most commmon problem with rough idle if that doesn't work EGR valve is the only other thing it could be other than plugs or bad wires or possably dirty
injectors however that sait i would start with the most ovious/inexpensive temp sensor it worked for me let me know how you make out Jeff,
