after two months of my CEL on, I finally have had a light-less dash for over two days. Usually it was coming back on the next day but it stayed off this time so far (knock on wood)

here's what I did

I had a P0171 and P0174 all through this....
1) I used seafoam and cleaned the IAC and MAS
2) I changed the spark plugs because I was getting a miss. Then cleaned IAC
3) I then changed the fuel filter because I had a miss at high RPM's
4) I cleaned the IAC for a third time and reset it with the battery.....

voila....thanks guy. This thing screams now.

Thanks guys!!!!!!!!!!!!!!!

ps...the first week I had the truck, a shop (rhymes with hidas) wanted to sell me $800 worth of parts for three bad o2 sensors....I fixed this for under $175 (and only that high because I had to take it in for fuel filter and plugs as I could not get them out)

do not buy anything from someone who reads your codes......
