Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi there, I am Cam. Can you tell me what issues your having with your Suburban?
How long does the new IAC work for when you install it?
Does it change if you tap on the housing of the ECM itself?
yes, that is correct.
Possibly yes. The fact it works after putting in the parts then it fails again, its likely. And those older ones are bad for issues. Tapping usually makes it fail quicker.
Check for wiring issues, rubbing and such like that around it, open the cover and make sure the MEMCAL inside is seated, make sure there is no corrosion and such.
