Still hard to start after AMM replacement

90 240 Wagon, auto, with 200k Started on first crank all the time. Nov 06 FPR started to go, replaced with new in Dec 07. March 07 Started to run poorly, no stalls, shakey at lights and stops while in drive . Checked for vac leaks , none. Check hoses and Flame trap, all clear. Replace injector seals, very small running improvement, but starting becomes worse. You could smell the fuel in the exhaust. May 07 Raplaced AMM with used one 007 model. Runs great, but idle is high. If I take my foot off throttle on level road car will reach 20mph and shift into second without any pedal. It also will not coast when pedal is released at higher Rates of speed, 60, 65, 70mph. The rpm's hunt high and low almost pulse like. And it is still hard to start, but with much less fuel odor in exhaust. I'm leaning towards injector problems. Poss O2 sensor. Going to tune it up and see what that does. Any ideas.
