Thread: High idle, decel issues?

The Diagnostics Dash in TunerPro for TunerCode is real handy for adjusting TPS voltage, idle speed, and timing.

So I've learned! :-). Just too lazy to adjust what needs adjusting. Now that I have an issue, it'll force me to fix others as well

Fixed.

Just adjusted my TPS down to .44v and unscrewed the idle setscrew a bit on the Q45 TB, and all is now well with the world again. At idle, I can rev and release and see fuel cut, where earlier today I never saw fuel cut on the display monitor.

Maybe this cleaned up my AFR a tad bit, going to go cruise it in a while and see what happens.

Excellent! As long as the TPS voltage is below 0.5V with throttle closed, your good.

ive had a few problems with the idle setscrew they can become a pain if the small nut bcomes loose and the engine vibration starts to move it i had alot of idle issues from stupid stuff like that
