Heya!

I think my Phazer has extremely high idle rpm, it sits around 3700 when started cold. What should be expected with these sleds? Mines a 07 Phazer FX.
 
When first started mine will idle around 2700 and drop down to 1800 when its warmed up.
 
Manual says warm idle speed should be between 1700-1900.
 
There isn't anything mentioning cold idle speed? The clutch engages at 4000, so it feels too close :p

Maybe I should check the TPS? I bet it's not in the correct interval.

It's completely regulated by the ECU when cold but yeah, at 3700, that's too fast. Check cable free play too. It shouldn't be tight at all. There should be 2-3mm of free play at the lever.
