CM New issue--idle when hot
Today was our first nice day in Michigan in about forever. Got up over 80.

Car was running great, but as it got warmer, seemed to have a strange issue. It wanted to stall. The idle was all over 1100-to 700-down to 400 and all I could do was apply gas to keep it running at lights.

Electrical? Mechanical? Evil spirits? Voodoo?

Any thoughts? Mileage and performance otherwise seem great. Whole fuel system pretty new and I run nothing but Top Tier Premium.

Not yet. Kinda jumped the gun on repairs with the weather finally nice. It's on my list for sure, along with replacing a noisy AIR pump. If this issue is related to the air rate, two birds I suppose, when I do reset it.

My big fear was something cracked. It was something I'd never seen before and noticed it when I came home from a cruise.
