High idle at start then normal
When I first start car my car it revs to about
1.5-2 rpms. Warms up then its fine.Also
notice a vibration in the steering wheel at
idle. One time I turned the heat on after
engine was already warmed up & idle
dropped very low. Please help. I do have a
check engine code for the evaporator which
mechanic said had nothing to do with the
idle.
