Ford F150 Heritage
I purchased 2004 F150 Heritage and have the po 174 code. It says system too lean bank 2. I don't know what that means and would like to get some advice as to what to be checking so troubleshoot the right areas first.
I bought a 2001 Nissan maxima that has been giving me problems ever since buying it. When I purchased the car I had to take it back because of a bad MAF. After I bought the car I started getting codes for all of my emission sensors. I first got a code to replace a pre-cat (600xx) The next code replace o2 sensor bank 1 sensor 1 the bank 2 sensor 2 (200xx+ labor) The next code replace the catalytic converter (2 right after pre cat) 500xx job. My car was fine for 2 weeks now I have another code for o2 sensor. wtf! what should I do keep replacing parts until i have paid for the car twice!?! i dont know what the right answer is and would like an outside opinion. the car starts drives okay but the light will not go away. i am up for inspection and cannot test until my dash is clear of codes. p.s. if i reset the light via disconnecting the battery it comes on as soon as the car is turned on. Please if you have any knowledge about this HELP!
