I agree with the above, stop driving it because you are clueless. I see 2 things happening. Scenario 1, the fuel is leaking in the enginebay and starts a fire, possibly a write-off situation. Scenario 2, the engine is being starved of fuel and running lean, the engine will run super hot and throw a bearing(s), melt pistons & valves, crack the piston rings, break the conrods etc, resulting in a rebuild that is going to cost 2k+.
