car starts ok but between idle an 2500 rpm it bogs bad...after 3000 it has all its rev back and runs fine..have changed fuel pump n filter,plugs n wires n cap,but no luck ....it just did this after the battery went dead after 4 months of sittn in a garage please help!!!!:banghead:

try unplugging ur throttle position sensor its on the throttle body and if it runs better then you know what the prob is but it might throw a CEL so dont worry or is the CEL already on??
