High WarmUp Idle

On my z6 swap, when its first started in the morning or after sitting long enough to cool it warms up at 3000-3500 rpms. Once it fully warms up it will idle somewhere around 700-1k. Is this warmup rpm normal? or is something not functioning properly? im getting a code 9 (no 1 cyl postion sensor) but it seems to run fine. maybe that is what is causing the high idle?

TIA

That sounds high to me. I think it's supposed to be somewhere around 2k.

when mine warms up its around 2 or so

any ideas on what would cause it?

Mine has been the same was since i did the mpfi swap a couple months ago. I cant figure out what is wrong with it, but it runs fine and I'm not getting any codes. Its just really annoying.

That is very high for a cold idle.
Check the wiring/vacuum connections @ the EACV & Fast idle control valve. Since you have a code 9, the distributor could be bad.

I was thinking the dizzy or its out of time...but I have no idea mine only idles at 1500 when cold but the car is crackhead anyways

when my z6 warms up its at around 2-2500 then fully warms to about 1k

When I first turn my car on and its cold it idles at around 2,000rpm also...but then after it warms up it goes down to around 1,000rpm. I dont like the way it drives and/or feels when it idles so high when in neutral.

Looks like this is a common problem.
I agree, its really annoying to have it idleing so high when you are just sitting there after it has warmed up.

Yeah i dont like when its up in the 2,000 range...i like it around 1200rpm or less.
