Dmgconst

I have little to no funds and need to get my Tahoe going. It's unfortunately also my residence at the moment... I have p0300 (freeze frame), p0135, p0102, p0650, p0135 (pending), p0155(pending), and another p0300 (pending). I cleaned my mass airflow, sprayed the throttle body valve, filter is clean, wiring appears to be intact. Like I said I have extremely low funds. Any advise tips or tricks to getting this figured out is a blessing. also not sure if this is where I was supposed to post this I'm new here.

What tools have you got available?

How does the truck run? When my truck **** the fuel pump it threw allllll kinds of codes, including MAF. Do you have a way to test fuel pressure and check spark plugs?

I have a decent amount of tools. I should be able to do testing.

In the truck sometimes will idle rough and run rough other times I started up and it seems to run okay but it damn sure uses a lot of fuel

We need to test fuel pressure, especially when it's idling rough

Cleaning a MAF generally does nothing except make you feel better, but let's check fuel pressure before putting a MAF on it

for the misfires: it's random right now, so I am pointing to fuel delivery as the culprit. Mainly because I've lived this life with my own Tahoe

You have other codes too, but right now I think 102 and 300 are the important ones and my guess is fuel delivery
