Whats going on guyz... Well my cel came on yesterday, the codes are P0455, P0171, P0174... 171 & 174 are lean bank 1&2 and P0455 is EVAP EMISSION CONTROL SYSTEM LEAK (LARGE). Would the P0455 cause the system to read "lean"?:icon_confused:

I have a pretty good idea what to check about 455 code, but what i want to know is if this code is the cause of the other 2 codes.

Thanks in advance guys.:icon_thumby:

My credo
If you can't go through it or around it, then go over it.
all i can tell you is I have spent 18 months chasing the same thing on my wife's minivan and it ended up being a cracked vacuum tube under the upper plenum.
