You may have a relay that is failing. Not sure though. Would be something to check until someone more knowledgeable got here.

thanks have a check engine lig now ....ahd coil pack go last month but i dont know if its another ?/////////////

Can you get that code scanned? That will help us fix that problem atleast.

got code 303 then changed plug and wire for # 3 code 303 still comes up even after it was reset miss fire still there

Pull all your plugs and inspect them. Look for fowling. Check all wires and make sure they are seated correctly. Check your coils to make sure they look ok. May I ask why your just checking #3? Keep in mind the coils fire 2 plugs each. So check that mate to that plug as well.
