It measures the air mass and it is useful for the ECU because it can calculate exactly how much oxygen is entering into the engine. With this information, the ECU regulates the engine parameters to ensure its right performance. The sensor is placed in the inlet manifold, just behind the throttle body.
Let me start by saying I replaced mass air flow sensor and fuel pump so far but the issue still occurs when I start the truck in the mornings it acts like it's not getting enough fuel but once it's started it idles and runs just fine if I start it soon after it starts fine as well only does that after a few hours of sitting. Anything you all recommend to check other than fuel injectors as those are gonna be tested today?
