i know they wine at idle, it wines extremely loud when it acts up, almost like the pump is getting a load on it, ill try to get ahold of a better scan tool, and thanks for the iac ill try it, but its weird, even when i get it to start it stutters like its starving for fuel and hitting the gas doesnt really do anything unless it gets up in rpm's, you know anywhere where i can get ahold of use of a good scan tool? thanks
