Im getting a trouble code on my 95 3.4 4x4 tacoma. Its a P0170 which isnt in my haines manual but the guy at autozone that read the code said it was "Bank one fuel trim". The truck runs fine but gets horrible gas milage. Can anyone help me out. Could it be an oxygen sensor, or would i get a specific code for an O2.

i have a 99 prerunner...and i had a similar problem a couple weeks ago. my check engine light came on but my truck drove fine. i had a friend of mine run a diagnostic and it was one of the O2 sensors.
i had to buy a new one. cost me $113 at the stealers and my friend installed it for me. you may need a new one.
btw...welcome to CT!...fill out your profile if you can

For an oxygen sensor try www.buyoxygensensors.com, 99.00 I think , also free shipping. I got mine from there, fast service.
