What could be wrong with 1989 Honda Accord LXi - automatic transmission Shifts fine when cold but when warmed it acts like it can't get moving in 1st gear but after enough sputtering it goes?

Answer 1

Car is fuel injected and has 242,000 miles on it. At first I thought it was the transmission, but since it shifts fine when it is cold, I think there is nothing wrong with the transmission and it is something that is more related to the electronic control of the flow of fuel -- when it is cold, the various electronic components which control the fuel injection and are designed to operate differently with a cold engine (idle speed is higher and less air gets mixed with the gas -- I think). The problem, however, begins when the engine warms up to operating temperature -- somehow the electronic components that control the fuel/air mixture are not giving out the right mixture information. But what part does it sound like that is causing the lack of fuel or firing when it is starting out from a stop sign? The engine doesn't die, it just acts like there is no power and it is "sputtering". Once it hits 2500 RPMs then it "grabs" and acts normally and has pickup to accelerate the car. And do you think my speculation is correct -- or could it still be the transmission?
