Heater deviling on heat when turned on
Is there coolant present in the hoses leading in and out? If so than there could be air bubble in system and it needs bleeding. I just fixed one with compressed air blown through heater core.

1st your fan motor may be going or something has fallen in the vents you will need to gain access for that, or it might be YOU MAY HAVE AIR BLOCK, OR BLOCKED HEATER MATRIX, CHECK FIRST CHECK THE HEIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN COULD BE AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS (TWO PIPES GOING FROM ENGINE BAY TO INSIDE OF CAR, AND FLUSH OUT WITH HOSE TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP, YOU CAN BY A COOLENT FLUSH SOLUTION TO CLEAN THE SYSTYM OUT

The valve seals are leaking. When they leak then oil drips down in the cylinder. Causing the puff of smoke. And somewhat fouls the spark plug. When you rev it up it cleans the oil off of the spark plug and then the plug fires properly.
