I have a 1998 ford expedition 4.6 L, W motor, got a engine diagnosis test done becuase of a rough idle when in park and backing up, had exhaust smell and alot of smoke coming out of tailpipe. Whiteish until care warmed up. , Paid $90 for test and it read code PO135- 02 sensor heated bank/sensor/ also PO401 egr, dpfe sensor, and p1131 lack of heated 02 sensor bank/sensor, switch indicated lean, cycl. 2 mis fire. I replaced the 02 sensor on the passenger side the one up front that they said. I also replaced the egr and dpfe. The engine light is still on. Has a little miss yet when at idle only. I had a remanufactured engine put in about 7 months ago. Im getting stressed out about this issue. I dont know alot about vehicles and having a hard time who to trust. Ford isnt helping. I dont want to uin the engine that was just put in. Any suggestions what the issue might be. Was there 2 sensors I was suppose to replace. Truck running a little better but like I said light still on and little hesitation or miss when idling. Help please if you canI have 207,000 on vehicle about only 6000 miles on remanufactured engine so far
have the same problem?
