So i got a check engine light, the superchip tuner said i was running to lean code p0174 bank 2... i know for fact i need to change the fuel filter, any other suggestions to run more fuel with that change. thank yall

2002 silverado 4.8

 

fuel pump isn't getting weak is it?

 

No I don't think so? I don't hear it whining or anything

 

That code could also be a air leak anywhere past the MAF, intake manifold, exhaust manifold would be a good place to look into.

 

could be a dirty MAF also..

 

ok cool thanks

 

Check your intake gaskets too. The factory ones were prone to leaking. I have had to change them on my truck and my dads truck as well.
