P1390 - Timing belt skipped one tooth or more.
the engine is an interference engine so if the timing belt skipped, it should be fixed before starting the engine again. otherwise you run the risk of bend/break valves from piston to valve contact

It appears that there might be a TSB (technical service bulletin) issued on this vehicle by Mitsubishi. Check with your local dealer to verify for certain. One link with brief summary of this on a 1998 model (yours might fall into this class too?) can be seen here and is as follows:
1998 Mitsubishi ECLIPSE 98 - Transmission TCM PCM > POWER TRAIN : AUTOMATIC TRANSMISSION : CONTROL MODULE (TCM, PCM) [Part 103100 ]
TSB No: 01 NHTSA ID: 622435 , May 01, 2001 : Replacement:
Summary: subject regarding diagnostic trouble code p1390 pcm relearn.
A fuller discussion on a 1996 with this code can be seen here. Scroll down to the answer.
Perhaps these will provide a bit of information prior to contacting your dealer. I've never worked in a dealership that charged for looking up & providing info on TSB's. Good luck.

This is the direct definition of this code
Mitsubishi DTC P1390 - Timing Belt Skipped 1 Tooth or More.
-Timing belt improperly installed
-Camshaft position sensor improperly installed
-Camshaft position sensor connector improperly connected
-Crankshaft position sensor connector improperly connected
-Camshaft's relative position not relearned after one of the following have been serviced: Camshaft, Camshaft sprocket, timing belt tension-er, cylinder head, head gasket, crankshaft sprocket, crankshaft cylinder block or the PCM.
Sounds like something to do with the timing belt it self. You can go to any Autozone or Checker and ask for a code reader (they will let you use it for free) and it will show this code again. You can also reset the cars computer with the code reader to see if it comes back with the same code.
