OBD codes p0171 & p0174
Hey Guys,
I have a success story that may help someone. I had these two codes so I changed o2 sensors and that didn't fix my problem. Next I disconnected a vacuum hose going to the intake and did a smoke test. My son gave me an
It's a boy cigar so I used that to make smoke ( I'm not a smoker and I had that taste in my mouth for 3 days, ugh, anyway it was worth it.) I found that the small hose on top of the intake had a very very slight wisp of smoke so I resealed the little grommet and the code scanner doesn't read those codes anymore. Hard to believed that small of a leak caused all that trouble. Hope this helps someone.
