Idles fine when cold, not warm

Idles fine cold, shakes warm, what sensors involved

Car idles perfect when cold, never more than 1100 rpm. Once it warms up, temp half way, I get engine shake. Just had it smoked and no vacume leaks. My guess is a sensor? Any ideas?

if you haven't done the pcm upgrade i would suggest that i had it done yesterday. i used to have idle problems hot and cold and the upgrade solved all my issues if you have any questions let me know

when you say idle problem, are we on the same page? The idle doesn't surge or fluctuate, it's juts rough, engine shake.

Is that what you had?

not IAC or pcv either. my guess something is getting by passed but what?
