Default 1991 Honda Accord Ex Wagon Check engine and acceleration problems

Hey all, I have a 91 accord ex wagon, and recently a radiator hose burst, it was one going from the block to a valve into the firewall (for the heater core, im assuming) anyways, i replaced it right away and refilled the coolant. When i started it right afterwards, my check engine light came on every second or third time i started it, so i put more coolant in, and that solved the problem of it coming on right away. Now it only comes on once i hit 60-70mph, and every once in a while my car will feel like its about to stall and i lose power and start slowing down as i accelerate. Im pretty lost on what this could be. My best guess is the MAP sensor? Not sure why my radiator hose going out would suddenly affect that, but anyways, does anyone have any ideas as to what it could be? Or any experience with this problem? Sorry about the long post, but i figure the more details the better. Thanks for any help.

-Edit- Its the 2.2 4speed automatic, and It idles fine and normal when im sitting.

you jumper the service connector with a paperclip and count the blinks...go to youtube and search for "how to retrieve check engine codes honda" then google "honda obd1 codes"

So it came up as 2 slow blinks and 3 quick ones, which i think is the code for the knock sensor, which is something ive never even heard of, does anyone have any idea where its located?
