My best word of advice so that you do not blow your motor is STOP DRIVING IT!
Then, tow it to a repair shop and have them diagnose it. You will have to pay to get it fixed unless you know a thing or two about maintenance. But if you want to keep your motor salvageable, stop driving it and making things worse. Please no dead Balt.
Not enough info to give you a diagnostic and there are too many things that it could be.
Any questions about the Balt, all answered here:
