Recently purchased 1991 base 900, have no previous records so i dont know whats been done in the past. Car is hard to start in the mornings, wont fire up right away on first few cranks. If i stop trying for a few seconds then try again starts right up but i have to keep my foot on the gas for about 2-3 mins to keep from stalling. Once warmed up the car hesitates when i accelerate and bucks when i decelarate. I am using 91 octane fuel. There is NO idle fluctuation at all, No fuel smell. Here's what i have replaced in the last few days:
1.New battery
2.New NTC transmitter (coolant temp sensor)
3.New NGK plugs
4.New Bosch Cap and rotor
5.New Air filter
6.Cleaned throttle body and Aic. Aic might be new because its really shiny.

Problem still exists, hoping someone out there can give me a suggestion what else i should check/replace. Sorry for long post.
Thanks,
Miko.
