Po174 code

[Destory racing]

I'm new to this forum I got a lean code sohc motor bank 2 only I have replaced the upper an d lower intake gaskets egr valve fuel filter truck runs and drives great. I got a pop at idel. Was thinking might have a bad injector. If anyone could help thank u

Bad injector will tend to cause just one cylinder misfire instead of that code. I'm wondering if you have the beginning of a head gasket leak and would do a leak down or compression test, and keep a close eye on coolant and oil condition and levels.

You might also check fuel pressure and clean the MAF sensor if it hasn't been done in a long time.

It's got a new fuel pump not to old at all I cleaned the maf it's just the one side i do have the kit to test for a head gasket I'll try that and let u know what happens thanks for the input

Could you get freeze frame data from that code? It could give some hints (is it idle, cruise, etc?)

What should I look for when I do the freeze frame? It does it at idel u can here a pop in the exhaust it has a flowmaster on it so u can here it when it does it. It is cosuming a lot of fuel to.
