Review on ACDelco GM Genuine Parts Fuel Injection Throttle Body 217-3108 with Throttle Actuator by Aaron Charlton

Bought for a 2006 Chevrolet Impala with low idle. No check engine light or error codes with scanner. Revain says this part does not fit this car, but the Autozone and O'Riely websites confirm this is the correct ACDelco part number ($100 off Amazon, sorry Autozone and O'Riely). Installed today and the car works perfectly. Previously I tried setting up new spark plugs and wires, decarbonizing my old throttle body and cleaning the MAF sensor. It also couldn't hear or detect any vacuum leaks with the smoke machine.
