I have a 2004 chevy cavalier. It has a new battery and alternator. I am having trouble with my car when i first start it, the battery light comes on, the engine idles fast and the head lights and dash lights flicker on and off. Once it idles down, all that stops and it runs fine. If I don't let it idle, it jerks when i put it in drive and it bogs down and runs slow until the battery light goes off then it runs fine. What could be wrong? Some say altenator, but it has been checked twice and seems to be fine. Could they have given me the one for a bio fuel?

you need a volt meter and check battery voltage before and after starting. before at least 12volts after 13+. if you don't have 13+ volts running the alternated isn't working correctly. also check voltage with battery light off engine running.
