Answer 1

Timing could be off or it's running really lean. Check your fuel pressure. Year and engine size would help.

Answer 2

I had a chevy pickup that when you shifted would shoot flame out the exhaust. This was caused by unburned gas being detonated when the exhaust valves were open it was outta time
