2002 Misfire All Cylinders | Have read other posts | Advice?

PO301 through PO306 codes. Triggering CEL + VTM-4 lights. Car has 175k miles.

Work performed after reading through this great forum:

-Valve adjustment performed by local mechanic in Portland, OR
-Coils replaced with ones from a 50k mile motor by local mechanic
-New plugs
-EGR port cleaned
-New EGR valve
-New air filter
-Fresh oil change
-Lucas injector cleaner added to full tank of gas
-Premium gas always used

Problem:

-CEL + VTM-4 lights still coming back on after clearing codes

Questions:

-Should I take to Acura dealer have them perform valve adjustment again? What else am I missing here or should I try? This seems to be a common problem…
-Is there a way to ‘disconnect’ the connection between the CEL and VTM-4? In other words, it’s a big bummer to needlessly lose AWD in winter months when the car seemingly runs fine and the CEL goes on. Thoughts?

Thanks!
