High idle after replacing iac on my TBI 350 5.7l V8 GMC Sierra
What is your question?
Replaced iac on the TBI of my truck, now it idles at 2200 rpm in park. Put it in drive it revs up to about 2500 rpms then drops to 1800 rpms. Once in drive it starts to accelerate on it own up too 55km at 2000 rpms. When I apply breaks it jerks and rpms drop to 1300, when breaks are released it will Rev right up and accelerate by it self again.
