About two weeks after i installed an MAC intake in my truck the CEL came on the codes were pulled and they showed P0171 and PO174. I have replaced the PCV Valve and cleaned, as best as i could, the MAF. Also my gas mileage has dropped drastically from like 65 miles per 1/4 tank to about 18 miles per 1/4 tank. ANY SUGGESTIONS ARE APPRECIATED!
