SOURCE: '97 A4 1.8T, coolant leak resulted in brief overheat,leak fixed,diag.code now shows #2 cyl.missing (badly), compression good,injectors good,coils/plugs good,missing badly,could the brief overheat have
did the car over heat for long?
there could possibly be damage to your head like warping due to overheating and blowing a head gasket or something along those lines .
first check the oil dipstick is it milky?
then check the coolant is it oily?
and when it is running is it blowing any white smoke?
if you replaced the plugs and it is misfiring did you plug the wire all the way back on the plugs if not then the problem is a plug wire being loose and loosing connection with the plug.
sounds like a simple fix if you don't have water in your oil or white smoke coming out the exhaust.
troubleshooting it can be a bigger job but if you nail the right symptoms down you can corner the problem.
like if it is a coil pack or bad wire switch them with another one and see if the problem follows the wire or coil pack.for instance take the number one plug wire off and the number two wire off and put the number one wire on number two and see if the number one misfires. if so then the wire is the problem if not then try numbers three and four until you find out which cylinder is the culprit.
good luck and happy hunting.

power not reaching cylinder 1 ignition coil. check electrical connections and wiring for any damage. test for power and ground at cylinder 1.
hope this helps.
