So I drove the puppy hauler today and warmed up it idled at 900 in park. It should be 700
No hoses are cracked that I can see. But the issues I had at first fire after the head gasket replacement I may spray out the IAC again. I am planning on spraying the crap out of the intake area with brake cleaner to listen for an idle change.
Edit: I'll add also I noticed the idle surge just a smig.
Tonight I started up the puppy hauler in park and it settled into a nice 700rpm idle hot and in neutral or park. Piss me off. I removed vacuum mine that tees to the intake and back flushed the IAC anyway.
