"and i do not need troubleshooting posts at this time" The OP likes his threads clean, it's tough to not put more thought into replies though.

with CFI-EFI....all the way, the IAC resets itself after driving, and I don't believe the IAC is your problem. NO comment about the brake booster

BTW, there are I believe three different pintles (couldn't find my source this morning..company) but I'd check it out before assuming a different year will work! And I believe that was your original question.
