I couldn't get anyone.

There was a tune on the car from JMS Chip and performance, I looked them up on Google and seen that they advertise the "fix" tune which eliminated the deceleration stall on the coyote... I read through lots of threads on some forums with coyote installs talking about exactly this tune vs speed dial.
I also knew a speed dial was added with the speed sensor to this car which was also for deceleration stall.

I read you do NOT do both, its one or the other and there could be a conflict with both so my options were to try to dump the JMS tune or remove the speed dial.

I disconnected the speed dial and the car idled perfect, about 1100 at start up and within a few seconds down to 650.
Took the car out for some extensive driving Sunday and Monday to test idle, stall, driving temp etc and it performed excellent... all came down to unplugging something.

Thank you again. Bob
