My Dad has a 01 Chevy S10 with a 4.3L Manual Trans. He is having a problem with the RPM hanging while he is driving. If he hits the brakes or clutch it will drop. He bought an IAC valve from Autozone but that did not fix the problem (I believe Autozone parts suck). One of the reasons I bought an EFILive was to help with this problem.

I figured I could BBX the truck during the problem (Maybe even pass through). What PIDs should I be loading and looking for?
