It may sound stupid, but check the reverse lever/button. I have had
occassions where my impact driver wouldn't work properly only to find
that the reverse lever wasn't all the way over and air was leaking.
With all the other racket you couldn't hear it.

I was just looking at the specs for the 2135TiMAX and noticed that the
specs say minimum hose size is 3/8", but the air inlet is only 1/4".
Air consumption is listed as 5 cfm, but it does not give an air pressure.
Anyway, if the air inlet is 1/4", why would it help to put on 3/8" qc?

^^^^^^^^^^^^^^^^^^^^^^
1.) You are aware that pipe sizes and hose sizes are not directly
convertible?
B.) The inlet to the tool is not as long as a hose so its size is not as
critical.

The spec give average air consumption. It is like rating duty cycle on a
welder. In reality the actual consumption may be two three times as much.
A QD is slightly restrictive. The 1/4" inlet will probably flow more than
the 1/4" QD will. I would try the impact with a larger hose and QD, or a
much shorter hose. One thing you can do is to see what the pressure drop is
at the tool fitting. Add a air pressure gauge at the tool and see what it
reads while using the tool. If it drops very little, maybe 5 PSI, your hose
and fittings are good. If it drop say 15-20 PSI you need more air, bigger
hose!
