HELP!!! IAC replacement troubles, is my car CALI spec or not? Options

[axelrduvirage]

my car is a USDM from the BOSTON area. i bought it a few years ago from a reputable used car dealer here in Nova Scotia. i am having trouble determining if my car is CALI spec or just pain ol' USDM. i need to replace the Idle Air Control (IAC) valve since i am having startup and idling issues. i called the local TOYOTA parts counter and after spending 20 minutes on the phone and giving him my full VIN, the "specialist" could not commit to placing the order since he wasn't sure the car is CALI or USDM. i found the TOYOTA part number on the IAC and he told me it didn't make sense since that was a CALI SPEC part number on a non-CALI car. he also suggested that it was replaced with the wrong part-- but there is a yellow lacquer mark across the top of one of the mounting screws (looks like a manufacturer's tamper seal). this leads me to believe that it is the original. if anyone can tell me how to confirm my engine is CALI SPEC i would appreciate it greatly. i can then get on with the diagnostics and repairs. if this helps, here are a few TOYOTA part numbers from the EGR/VAC "plumbing":



1999 2.2l 5sfe automatic



IAC 2270-74291

EGR 25620-74310

EVM (modulator) 25870-74090

MAP sensor 89420-20300





thanks
