HELP!!! 96 F-150 with 6 cyl. I need some help with these codes.
P0172 says bank 1 to rich, P0174 says bank 2 to lean, P1151 says lack of 02 sensor indicates lean.
What would cause bank 1 to rich and bank 2 to lean. And P1151 really throws me off.
Could this be the Mass Air Flow Sensor or am I just waisting money.
Thanks, I'll try that. The reason I'm asking about the MAF sensor is because Autozone said that the codes pointed to that. I bought one and plan on replacing in tonight.
A lot of times a dirty heating element in the MAF can cause the engine to run lean. Clean it before you replace it. Best way I found is to use some rubbing alcohol and a q-tip.
