engine misfire

im asking for a friend of mine.
hes got a 90 dx hatch with a ZC. as far as I know about his problem is that his motor is misfiring or something like that. im not sure as of the meaning of that but all i know his car drives like crap and it would stall sometimes. hes not sure what cylinder is messed since his battery died and he cant check the compression. (car hasnt been driven for months)

i was just curous about how would you fix this problem, and possibly how much it would cost to fix?

if only 1 cylinder is messed up then its usually either the spark plug or the spark plug wire or maybe the distributor cap

yup i agree .... but one thing... how did his bat run out ???? was it jsut a fact that he left it standing for so long ???

im not too sure about his battery, he said it may have been his alarm that drained his battery..

so it could possibly be a spark plug or dist. if its one cylinder? hahaha
he hasnt driven the car for like 4 months because he thought it was a bigger problem..

i'll find out today what the prob is. thanks for the info!
