Cold start power loss

Hi, I just bought a 1987 Toyota Supra N/A auto with about 170k miles. The problem is, before the car fully warms up, I have a lot of power loss when I try to drive it. I can put my foot halfway to the floor and its barely getting up to 25 miles an hour. Once it is warmed up it runs great though, a lot more power everywhere. What could be the problem? Thanks
By the way, has new spark plugs, oil changed recently if that helps. I know however it does need the tranny fluid changed and Im not sure when the last time the fuel pump was replaced.

I kno this is old post but nobody replied and i have the same problem he described. Im wondering if theres oil in the spark plug valley, maybe when its cold its not fully combusting, but when the oil warms up it conducts better....
any thoughts anyone
