Hi guys just thought id do a post with a few bits which i think would benefit people,
Its a work in progress so hopefully it comes in handy for people. If anyone has suggestions drop me a PM and ill update
I do not take credit for any of the following, The credit should be directed at the owners of the video who have taken the time to provide the info. If anyone does attempt any of the following that then is at their own risk
Exhaust Gas Recirculation
The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.

Mass Air Flow Sensor
A mass air flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine.
The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each piston stroke
