Honda Accord malfunction light stays on

my problems all started after I jump started my car, I drove for about 500 yards and I felt a jerk in the acceleration, the malfunction light came on and has stayed on ever since even after restarting the engine. my engine now cant tick over steadily it falls to about 100-200 revs instead of about 600-800. the honda manual mentions the emmission controllers, what ever they are?. can any body help or has had this problem before?

thank you in advance
