Re: iac valve location on an '05 2.2l ecotech i4
Is it electric throttle? If so, it won't have one.
That is, is there a cable to inside the passenger compartment, or not? If so, the IAC will be in the same general vicinity as the throttle plate. If not, well, it's all handled by the ECU and there is no IAC.
335K miles on original motor and tranny (only motor work 2 x LIM replacement), Monroe SensaTrac struts front and back (new at approx. 300K miles), and Alero discs in back. LS fogs added with custom wiring. HID high beams, HIR low and halogen fogs. Raybestos Pro Grade front rotors and Bendix D747 ceramic pads on front.
Addendum: Rest in peace. Surge tank blew, motor overheated, I think she's lived a long and useful life.
