Next week, when I am on vacation, I plan on doing a lot of work on my truck. I will be installing a new Specter air filter, new spark plugs, new PCV valve, new fuel filter, new fuel pump and a Flowmaster Super 50 muffler. My main concern is how will the engine react to so many changes all at once? With a new fuel pump and fuel filter, the fuel should flow a littler better but more specifically, the new air filter and muffler will drastically increase the air flow that the engine is not used to. Will this many changes all at once dramatically confuse my engine or computer? There was a sheet of notes that came with the new muffler that said the on-board computer is in a constant state of learning but with a new muffler, the battery should be disconnected for a couple of minutes after installation to reset the computer due to the increased airflow - again, I am installing a muffler and a high-flow air filter. Is resetting the computer all I need to do or are there any steps I should take before and after installation of all this stuff? Keep in mind, I have never done this much modding to a vehicle before so I am venturing down a new path and am looking for all the info I can. Thanks!
