It stumbles severly on take of and at each gear shift! hooked up code reader and keeps showing a code of 0303 and now its also started showing 0404 which is misfire on cylinder 3 (0303) and on cyl 4...

Probably is just time for a tuneup, unless one was recently performed, then in that case you may have gotten those 2 plug wires crossed. Another possibility is a blown headgasket which I've seen is fairly common on escorts. You may want to check for any broken, cracked, or vacuum line that has come off.
