CEL on and driving me crazy.....
So my CEL has been on a few weeks. Took it to autozone and the code reader gave me P0171 and P0174, . my truck is a 1997 Ford Ranger XLT 4.0 V6. Ive read on here another thread that had the same problem but I believe was on a 2003 Ranger. My question is can anyone tell me where to find the "cracked" elbow on my truck? Or if this is a common problem on Ford Rangers before 2000. And I have changed the MAF sensor, CEL stayed off two days then came back on. Gas Mileage slipping. Thanks
