Clean the throttle body.

Check for loose bolts at the compressor overrun valve. I eventually ended up with grade 8 socket head cap screws, lock washers, a new gasket, and red loctite to hold the sucker together.

Potential vacuum leak at the AMM to compressor hose (expensive part...>$100)

Probable leak at the AIC to intake tube hose.

Possible leaks at the intercooler intake/exhaust hoses. I use a third hose clamp in between just slightly tight to inhibit pressure bulges.

If the car doesn't respond immediately to throttle it's almost certainly a vacuum leak due to deteriorated induction hoses. The car IS 14-15 model years old.
