Last night when turning engine off, RPM's rose from 600 to 700 and then shutdown occured quickly and suddendly as usual. Did same thing today. The rush of fuel is very short, lasting ~1/4 -1/2 second. Am guessing about the 100 rpm increase as the electronics are off as soon as the key is turned off.

No leaks. No CEL.

Shutoff valve and K40 are both 2.5 years old.

Has gotten colder here this week, down to 30 at night. Has felt a little sluggish in the morning which I attributed to the colder weather, now am not so sure.

Am thinking this is shutoff valve related.

Can anyone confirm?
