Hey, my idle is really bad. but ONLY when its car is at normal operating temperature. It goes up and down maybe 400 rpm. no tacho so not exactly sure.

When i got my pink slip the mechanic suggested it was possibly my idle motor (never heard of that before) but hes not exactly sure. I would have to bring it back in to get it looked at.

Some one suggested before it could be my spark plugs, but i dont see how, because it ONLY happens when it fully reaches the normal running temperature. (always exact same spot on temp gauge)


Any help would be appreciated, thanks.
