Winter is here (almost) so Black Beauty is hibernating. Now I am trying to make things right with my winter DD.
It's a 96 Chev 1/2 ton 4x4 with a Vortec 350. I just changed the battery out and now it has a crazy fast idle. When I start it, it winds right up to about 2000 rpm and it won't kick down. When it warms up it then winds up to about 2500. I havn't done anyhting to it except swap out the battery. Why is it revving so high? It ran just fine before...
