Trying to solve P0171 and P0174. Sometime I get one, sometimes the other, sometimes BOTH. Waiting to see the results of cleaning my MAF sensor I was reading some old threads on these codes. My 99 Ranger is OHV and another thread discussing vaccuum leak in a PCV hose dealt with an '02 (SOHC). Here's a picture of the driver's side rear of my motor. #1 goes to the PCV valve just below and out of sight in this pic. #2 goes to the brake booster. #3 appears to split into two hoses that are wrapped in a protective coil. Question is where do they go? Are they a likely source of P0171 or P0174 issues?
