IAC question.

[andycrips]

Hey Everybody,
Had a quick question about the IAC numbers on the scanmaster, will they fluctuate while idling? The numbers on my scanmaster have been going from as high as the 200s while idling to as low as 00 with in a few seconds, I replaced the IAC this morning with a new one, it seems to have helped a little but it's still going "crazy". I have searched the forum and can't seem to find anyone with a similar problem. Also sometimes when it's idling the scan master flashes 27.5 on the retard degrees. Kinda lost here. Thanks for everyone's support!

Also, I have two MAFs and have swapped them with no changes :-/

Just did mine.
Reset the ecm
Back the t.blade screw out till it does not
Touch then set your numbers 15-30
Then set the tps to .42

Numbers jumping. Ck the connection on the s.master

How do you clean it and how do you adjust the IAC numbers? The IAC value is the only number that fluctuates, thank you for the reply!

The throttle screw will adjust the iac
I did mine with a small detail brush and carb cleaner. ( the inside seat for the iac )

Awesome!! Thanks a lot guys! I plugged in my laptop to my Powerlogger and it smoothed out the numbers and now I know how to adjust this, so I should be good to go now, thanks again for the help!
