Hey guys,
My truck shows "Check Engine" light. When I had the code read it said MAF Sensor Fail. I probably had my K&N over oiled and fouled the sensor. I attemped to clean with alcohol since that is what a shade tree mechanic told me to do, but still shows a fault even after getting reset. Is there an aftermarket part to replace the sensor or delete it? I dont mind a little smoke.
I am also looking for a EGR valve delete kit. Never messed with one of these things before so ANY advise on this will be appreciated. My truck has one for sure, I checked.
Last thing, I tore loose the two front wheel speed sensors when I removed the lift kit from my truck on accident. I rewired them but still throws a fault. I am replacing them with aftermarket parts for a lot less than I would pay at dealership. Does anyone know if this is a simple project? It looks pretty straight forward to me, I know I will have to get it reset after but that is no big deal.

Thanks in advance for ya'lls help.
