Well. I am hearing a  elouder than normal” air flow noise recently. It only happens when I step on the gas (accelerate). I didn‼sup>TM</sup>t see any fault codes yet. Perhaps, there might be a small rupture somewhere along the hose but not big enough to cause fault codes, could that be possible? Need advise! Thanks.

pull the hose and inspect.

exactly the same and it's very annoying with a CVT that maintains the revs. I made a plug for the 2" dia air hose from the filter box to plug it then tapped into the manifold to input air pressure. Only found a slight leak at the connector on top behind the manifold - no obvious whistling leak like I thought I might find. I think I input about 15 psi but the gage on my compressor is not very readable. I was nervous about putting in too much...

the small elbow shaped hose (1/2" dia) connect at the back of the intake manifold. Mine (and others) was found to be split at the seam. It throw no codes also.
