engine codes?

I recently got a 0174 and 0175 code in my 2k rodeo.After about a week I got the 0172 and 0173 rich and lean in both banks. It runs smooth but is using more fuel. I could use some help on this as I can't really afford to take it any where at this time :confused:

There are several possible causes. Defective or dirty MAF sensor. Cracked intake manifold gasket, broken or leaking vacuum lines or vacuum leak between the MAF and throttle body. If it is the intake gaskets leaking and you are the original owner, you can have them replaced for free at the dealer. If there are any Isuzu dealers left, that is.

thanks. I don't know if it will be the maf. It started a week ago with codes just for bank 2. Then yesterday it pitched codes for bank 1. I hope its just the img. I have it in the shop:mad: to get diagnosed. I got a deal from a buddy .
