Well, I have a problem with the Mountaineer keeping the engine running. So far, I have changed the fuel filter, and I know that I am getting 40 psi at the test port on the fuel rail. I cleaned the IAC, and I changed the air filter just in case. I plugged in the backup computer just in case it was the Apten chip, which I switch back to stock when all of this started. I also know that this problem didn't start until I filled my tank with 20 gallons of fuel this morning.
The vehicle fires off immediately, but has a hard time staying running, if I can keep it running. I know that the few times that it will actually idle, opening the throttle body might let the engine rev to 2000 rpm, if it doesn't kill the engine first. In those cases, the engine will actually run better without pressing the gas.
So, am I looking at bad gas, a bad mass air sensor, a leak, or what?
