starts to idle at 750 rmps what should i do an what is the problem? please help me...

i was thinking about chanhin my sparx plugs an sparx plug wires for a longer lastin life.. will that help my
situation?? :(

Your rmp's are fine... and so are you rpm's :)


You idle higher with a cold start. After your engine is warmed up you should be around 750~800 rpms.

I believe when I fire up my car its in the same range as yours.
