Hello and welcome! My name is ***** ***** I can assist you with your question. It sounds to me like you have either plugged exhaust, a bad cam ro crank sensor or the mass air flow sensor is bad. Glad can help!
No not nessarily. There is no code for plugged exhaust. In addition, you could have low fuel pressure do to a weak fuel pump. There is no code for low fuel pressure.
Be sure to check the air intake snorkle from the mass air flow sensor to the throttle body to ensure there are no cracks or rips. Is everything checks out good, the most likely possible cause would be a bad mass air flow sensor. Just be sure that the ignition components are in good shape and are not misfiring.
Right, if it were a "lack of fuel" then adding alternative fuel (such as carb cleaner) should help. If not, then no, the problem is not a "lack of fuel".
Usually plugged exhausts are a constant problem.. not intermittant.

You can remove the front oxygen sensors to see if that helps or you can check exhaust back pressure using an exhaust back pressure tester. It screws into the oxygen sensor whole after the oxygen sensor has been removed. The specs are no more than 1.5 psi at 2000 rpm.
This is the one I have. It works great.
