Codes P0171 and P0174.
07 tahoe LTZ
Thursday, cel came in and it was p0121. Pulled code with Scangauge, and due to it being wifes vehicle, I had to take it to the dealer. Dealer performed cleaning and relearn (pcm), along with other issues under warranty not related to this.
Saturday night the light appeared again, and it was the 171 and 174. I cleaned the MAF with electrical cleaner, replaced the filter, and checked for any loose connections. The vehicle seems to idle fine. Should I clear the codes, or? I see some other concerns in regards to intake gaskets leaking, fuel pump issues. I do not want the wife on the road with the current issues (holiday driving, three hours).
Thanks

Welcome to the forum...
If you have performed the recommend repairs for the codes you had, yes I would suggest your clear them and see if they return.
Unless you are have noticeable driveability issues, I would thing it should be fine for any road trip...
