Every time I start my car it spudders and feels like its missing. If I dont give it any gas it will stall. So I usually have to rev it up untill it smooths out and than its fine. Any ideas as to what may be causing it. Ive changed the fuel filter, ran some seafoam through the fuel system and changed my plugs wires and cap & rotor. Its also not throwing any codes.

 

Cleaning out the FITV (Fast Idle Thermo Valve) and IACV (Idle Air Control Valve) on the backside of the upper intake manifold may help things and wouldn't hurt either. Search the DIY for that info, and the link in my signature is an alternate search since the forum search might be broken still.

 

Post car info in your signature please. Have you read the codes or just no CEL? It could be a lot of things .... look in the DIY section for ideas on what to test
