i replaced my time belt about 5 months ago, since then i had gotten an intermitent rough idle that normally straightend itself out. now i have a code for a misfire on cyl one and it doesnt come out of the rough idle and when i step on the gas somewhat quickly my cam shaft shakes! i have replaced my coil within the past year and i regularly replace my plugs and wires also i have always had a code that says something about the auxilary input of my vehicle spd control but my car ran great for two years until this new idle problem came up?
