Hello, if you keep your foot on the gas, does it stay running?

Do you have access to a scanner? They are around $20 on Amazon and should be the first step in tackling the issue. It will help inform of any trouble codes in the memory. Next step is that we need to check that fuel is being delivered to the rail and is pressurized. Please let us know.
