It fits the needs that I had to better understand the diesel process
KENT MOORE TOOL J-37027-1A IDLE AIR CONTROL MOTOR DRIVER
10 Nov, 2020
IAC controller
I been having a really weird problem with a 2002 Buick Century 3.1L. The idle speed starts to climb without any apparent reason and along with RPM GOES the IAC counts, AND TPS % AND VOLTS.
With the J-37027 I'm able to bring the counts to where I want. I can change it up and down.
Hasn't solved the problem but makes it manageable.
So far no one has been able to tell me what is going on with this car
Great product
