Have you had the vehicle checked for fuel leaks? Do you ever smell gas when you get out after driving it?– finleyarcherFeb 5, 2018 at 21:25

No fuel leaks so far and I already check the front lines to the injectors and from the gas tank too.– KiroFeb 6, 2018 at 0:10

Please provide fuel economy numbers before and after. Knowing the difference will assist with narrowing down what it could be.– iDriveSidewayzMar 14, 2018 at 11:56

My car have 127,000 miles on it and I always use Shell gas 91 octane and I don't think my intake valves are bad and thanks for the thought– KiroFeb 7, 2018 at 14:12
