Has anyone ever had a noise coming from the area of the Throttle Body? It sounds exactly like when a power steering pump is low on fluid, that buzzing, groaning kind of noise & it goes with the rev of the engine. (It's not the power steering pump, that's quiet
) Could it be the actuator buzzing away? BTW, it seems to be focused in that area, while I haven't pulled the belt, the pullies seem quiet. Any guesses? Thanks. Also, I'm right at 160,000 miles (05 V8)
