... then ran "ok" on the way home. Not as good as normal, but just good enough to get home. After getting home I pulled the code and got a P0171, which is; P0171 (M) System too Lean (Bank 1) A lean air/fuel mixture has been indicated by an abnormally rich correction factor. I had an aftermarket ...

A true scan tool that shows live data yes! a code reader that saves only freeze frame no not really! There's a HUGE difference between a code reader and a true scanner. Code readers are fine for saving freeze frame data provided it's accurate data and spitting codes. What you want to know is the fue...

You don't have alot of money to be w...
