You can find what the codes mean here

May want to double check the 537 code, I don't see it listed in the link or in my manual.

It will help people to help you if you describe what kind of problems your explorer is exhibiting.

when i start it up it start's bogging real bad for a few seconds then it's ok there is a hesitation on the gas pedal, say that i stop for a stop sign then i give it gas to go u can feel the hesitation, like it bogs for a second then it goes, and when i drive around for a while the engine light comes on and sometimes go off while i'm driving, i have been driving it for 3 days now and no change at all???
I replaced the fuel pump and fuel filter underneath the vehicle and fix the air intake hose it was ripped i fixed it with a plastic sheet and some tape before driving the vehicle around

I would probably start by focusing on the KOEO/KOER/CM 122 & 124. Throttle position sensor (TPS) is a basic potentiometer and is pretty easy to check with an ohmmeter. Mainly looking for a reasonable resistance through the resistor, and that the variable leg changes resistance smoothly as the throttle is moved. Also, make sure the TPS is getting the 5V reference voltage from the PCM.
