If you need or think you need an IABV (Idle air bypass valve) (ETC6660), you know how expensive they can be. $150-250. After market ones are available, but difficult to find the right part number. Today I got one from AutoZone using the AC Delco part number. #25527077 . AutoZone can look up your RRC in their computer, but the recommended part must be ordered @ $250. The AC Delco # produced a part by"Wells" #AC102 (on the box). The AZ # is 002987 $36.99. The parts match, side by side, but you can see differences in the manufacture and quality. the original is better. Fits perfect, comes with instructions, and has a 3 month warranty from AZ. Such a deal!
