rough cold start idle

Typical question, read many posts, still asking for thoughts:
89 900 3dr n/a 16v. 190,000
Recently started occasional rough idle on cold starts, smooths out when warmed up, occasionally goes high idle (1500 - 1900 rpm) when driven long time.
Couple months ago I cleaned/WD-40'd AIC, cleaned throttle plate. Vaccuum hoses seem good, replaced grommet/o-ring on valve cover when I did the cover gasket a few months ago.
Also getting occasionally slight but noticable hesitation accelerating in 2nd, 3rd gears.
Looking to narrow down... AMM? Before I hunt down and/or buy another one, and/or try the Bentley test on the AMM, thoughts, opinions?
Thanks,
SDBWORKS
