Hey Azine Community

I have a 2007 Acura TL @ 131k. An emissions Code of P0171 came up on the Navi system. My TL Fuel consumption is somewhat high I am using 93 Pre (I am hearing not to use 93 only 91?) & theres sluggish-ness when the pedal is pushed from 10 to 30 mph. The problem is that, theres no CEL on the dash & the code hasn't come back since mid Feb. What is that code associated with as far as replacing? Mixed reviews I've heard are 1 of the bank Oxygen sensors, or EVAP Canister? Trying to narrow it down. Ive attached a Photo of the code on display. Thanks AZ Community

 

whatss up buddy i too had similar problems with that p0171 if u search for it on this forum u can see the history of my conversation as well as other who had this problem
but i had this problem 4 years ago and it came back i narrow the problem down again after doing the valve adjustment changing 2 of the o2 sensors the culprit was my fuel pump i put a new one in over the weekend hoping this light doesnt come on anymore . but the last time i had this problem was at 57k now im at 122k. but yes my fuel pressure was low so it was a faulty fuel pump so im going to get a whole new unit.
