Hard Cold Start Slight Miss in Idle When Warm (500sec)
 

well...there are a couple of strange things going on i am hoping some of you good people out there may be able to help with. First, it seems in colder weather the engine just strugles to start. It will turn over and hit...but seems to idle very low and run rough for about 10 seconds. Cold start Valve? Also, when warmed up there seems to be a slight "hickup" in the idle, just bearly there, but upsetting. It has new plugs, wires, distributor cap and airfilter. Are these two unrelated problems? I really appreciate anyones suggestions and help.

Thanks Scott L.:confused:

do my thoughts on the cold start valve seem correct? what might the cause of the "stumble" in the idle be? anyone....
Thanks Scott L.
