Ms3x - What am I doing wrong?
Hey, I have got the car running pretty solid before, but I had to revert back to stock for CA smog and then put back all the megasquirt parts and I am getting some really weird issues.
Car was idling at 3000rpm, idle screw all the way in.
Adjusting the IAC valve was making the rpm go down and not up.
Got the idle to about 1300rpm by fidling.
Won't get out of idle VE table.
I believe it was the IAC valve was making a horrible ticking noise at anything besides 0 steps in the output test.
Car is stock, 1990 miata, just has headers.
-Stock ignition and fuel.
I am nearly 100% sure there are no vacuum leaks or issues with anything as the car was running perfectly fine beforehand. But it almost feels like the car has a vacuum leak.
