The car has no power - does it idle OK? Does it rev OK with the engine unloaded (car not in gear)?
I assume you've done a visual inspection - no wires off, distributor not loose, no obvious missing hoses. Does the car sound different? Any loud hissing sounds? If you try to rev the engine, does it sound different, throaty? If so, look for missing hoses. Check the short fat hoses between the intake plenum and the engine. Follow the air hose all the way from the air filter, to the turbo, through the intercooler, AMM, intake.
Does the car run OK - not lumpy or missing, but smooth like at least all the cylinders are firing?
Pull the spark plugs first. Gap right? Do any of them look wrong? Any looking wet with gas, black with rich running, white with lean running? Any reason to suspect the ignition wires? Pull off the distributor cap - does the rotor look OK?
Disconnect the AMM - does the car run any better? It won't run right, but if it at least will move if you nail the gas, suspect the AMM.
