Before you change out the fuel filter and crank sensor you need to diagnose the issue. You have a misfire and that's why the exhaust smells bad. This can be caused by an ignition component or a fuel related issue. You can start by pulling the spark plugs. If you find one that is fouled out that is likely your misfire. A complete diagnosis is needed regardless so If you don't work on your own cars here is a link to find a good shop near you, https://repairpal.com/repair-shops Alex

Just as a side note - some of the aftermarket distributors are junk! ▪️3.3L V/6▪️
