AMM = Air Mass Meter.... less likely to be on a post LH2.2 car... It sits between air filter and first intake tube to turbo - a squarish box with a wire coming out the side. Also check the function of o2 sensor if giving hesitation off the line when warm as AMM had more control over ECU when car is cold... takes a few mins for o2 sensor to heat up. Use a digimeter and Bentley manual info to test.

The AIC is the automatic idle control valve and sits at far end of fuel rail - a brassy coloured object. It may need a good clean out using something like carb cleaner.

Also try towsend imports website for more troubleshooting>> link below.
hope that helps
