Question about 1996 Ford Ranger SuperCab
Engine light is on and code P0171 b1 came up when i did a diagnosis test on it.a freind did test but he don't know what it means.
How do i find out whats the problem?
P0171 - system to lean - bank 1 try this address and it should explain what you need to know...(There is probably some stuff that doesn't apply though)...upon further research I've seen many people pointing to a bad o2 sensor causing this code to appear so that may be the issue.
hope this helps.........Good Luck!
