IAC Question
IAC Question I wanted to make sure my IAC was working correctly. When I cold start the car up, the IAC is ~170 and it slowly works its way down. The IAC will settle to 40 when the car is hot. I get a little bit of surging during cold starts and wanted to eliminate the IAC. Hot starts are very good. The VE tables are set to 50/65/80 for 400/800/1200 and the F/A has also been adjusted.
Take a look at this thread:

I think the best thing you can do is reduce the authority of the IAC with the TB set screw, but not take it out of the system.
