Stage II owners (Normal RPMs)

[QuadcityDMC]

I have been driving around and found my car likes to idel at 1,500 rpm after it has been running for a while. On first start up it idels about 800 ish. Is the 1,500 rpm normal for the Stage II or is there adjustems that need to be done. Its going to be a year old soon and just want to make sure its supposed to do that.

Stage II or not, the idle should be the same as a stock(or close to it). I would imagine that almost every D is different, but I would expect idle on a warm engine to be around 1,100-1,200 in park, 8-900 in gear.(the AC compressor being on will also effect the idle)

I believe the exact numbers are in the tech manual, but 1,500 seems a bit high, especially if that's in gear.

If you have the stock idle speed control system, the idle should always be 775 RPM hot, cold, AC or not.

I have a Spec 2, not Stage 2, but my idle (I'm using the stock idle speed motor in my EFI setup) stays at ~750 RPM.

Does your idle go back down if you flick the throttle?

sticking throttle spool.
