It could be a bad AMM. You might also have a bad Fuel Pressure Regulator or a bad NTC sensor. All of these can cause rich running at startup.
A good test for the AMM is to swap in a known good one - Make sure that the part number on the black cover ends in 005.
For the jumping up to 2k RPM, it might be a misadjusted or intermittent throttle position sensor.
It's not such a bad idea to clean the AIC, but I don't think it's the root of the problems. The AIC doesn't affect mixture conditions.
