2011 acadia when taking foot off the gas pedal there is a knocking noise


The front motor mount and the upper engine strut mount both commonly fail. Start engine and have someone rev engine and let off while you look to see if either mount is moving excessively. The noise you are describing it is likely either or both the mounts.

Listen to the engine, if the noise is down low it is rod if it is up high it is valves. IF it is rod knock it will eventually throw the rod.

The engine has a nkockig sound..could this be caused by a bad knock sensor?


No it isnt a knock sensor the knock sensor job is to detect a knock noise and ****** timing. The knock that it is looking for is from octane or fuel or pinging that creates N0X s. A pollution gas. The knocking noise that you are hearing is different. If it is a multiple noise ar a rattling sound that will be the valves. There are other noises like a piston knock this knock is a sharp metallic noise, If the knock occurs only on acceleration that noise is a crankshaft noise. You need to check you oil level and make sure it is corrects. Look at the oil condition do you see silverish or whitish condition,is the oil deep black.
