-Your gas cap has to fit properly to seal-Have the exhaust system checked for restriction and also the fuel pressure

A fuel pressure gauge will tell if there's a problem with the FPR, Fuel filter and pump-for the exhaust use a pressure gauge to check the exhaust system for excessive backpressure-I recommend you just bring the vehicle in and have it further checked out by a pro.
