You have an internal transmission failure, have a transmission repair shop look at this and be prepared to have it removed for repair and rebuilding.

check transmission fluid level- run/drive for about 10 min. , park car- check with engine running- add fluid if needed- ,if fluid NOT low- transmission filter needs to be changed

That is a fault indication for your transmission. I am not positive but I think that indicates a fault in your forth gear solenoid. Your transmission is not going to last very long driving it like that. When you stomp on the gas and it does not accelerate, your clutch discs are slipping and burning. It won't take much of that to ruin them. You may want to take it to a good Honda transmission place. I don't know about the older Hondas, but the newer ones don't have any provision for removing a pan and working on them. They don't even have a line replacable filter.
Check your transmission fluid dipstick. If its not a nice "bright" red color, you are probably burning up your clutches. The darker the fluid, the more contaminated it is.

I just had that exact same problem. (1992 honda accord lx) It was the main relay also known as the fuel injection switch.

solenoid you have to replace them and they r expencive

i have a 92' honda accord lx, it has a problem of the D4 light flashing and the car wouldnt start, but i could wait a few minutes and try again and it would start.

control module sends the signal to the solinoid.So if it is shifting slowly then the solinoid is at fault Its moving to slow.

you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem

Blinking light means there is a trouble code.There is a procedure to manually pull codes from the computer.Have the codes checked,have them written down.It could be just shift solenoids,or could even be something more serious,but thats the starting point.
