skipping stitches, which is the problem you described, is most often caused by a dull needle, the wrong size needle, or by an error somewhere in the way it's threaded.
double-check to make sure it's threaded correctly on top.
set your tension back to 4, which is the factory setting.
double-check to make sure your bobbin is dropped with the thread pulling out counter-clockwise (thread pulls from top of bobbin and heads to the left.)
hit the C button to reset your stitch width and length to the factory presets.
change the needle. (use an 11 or smaller for piecing if you have one.) use either a needle from the pack that came with the machine or a shmetz brand. (there are other brands that work, i'm sure, but my janomes love shmetz and they are reasonably priced so i've never bothered to try any others.)
