look for a leaky fuel line
If a car begins to smell like rotten eggs and then starts acting like it has bad gas, it may have been filled with the wrong type of fuel. This smell is common when diesel fuel is burned.
Typically this is caused when the fuel is burned uncleanly and the sulfur in gas makes it smell
