is it common for a turbo ls/vtec to idle rich or lean, or does it differ with each car? my plugs are showing white, but i've been trying to get different things on the motor hooked up correctly and haven't had the car out of the garage. so all the running it's been doing has been sitting still. could this have something to do with it? also, my intake air temp. sensor isn't hooked up, and i'm looking for how to do that( b16a1 intake and head)d?
