Rough idle could bea lot of things. I will tell you the basic things that cause it. -Vacuum Leak -Not Enough or too much fuel or air caused by many things. Timing incorrect. -Bad sensor. (O2, MAF, MAP, IAT, TPS, CPS, to name a few) -Misfire (Tons of reasons) -Not enough grounds or bad wiring. *Lance*
