Check Engine light
Used coder to find out that my maf sensor was bad or so I thought. Changed it and reset the light and around 30 miles later it came back on with same code. Sensor was brand new so what else could cause this ?
Trying to sell this truck and so far the only time it was looked at the light was off. I know it will raise alot of questions just need some help.

Fault codes do not tell you what part is bad. The code requires interpretation to understand what failed and what parts may be involved, nothing more.

I can't remember the code exactly, I borrowed the tester from a friend and would have to get it again. But I can remember it saying that the MAF sensor was dirty, and/or there was a rich/lean running condition. That's all I can remember. Any idea's ?

code 171 and 174 for example--- MAF OR vacuum leak---- look for small 1/4 inch hoses that are hard and brittle- cracked.
