Engine starts and cranks fine, it intermittently sputters at 2,000 rpm, and intermittently idles rough like it’s starved of gas. Changed fuel filter, cleaned maf, don’t know how to check fuel pressure but I have the kit to do it. I tried to use the fitting on the fuel rail and an adapter but nothing was showing. Unplugged the IAC valve at warm idle and it dropped from 700 to 600. I’m guessing PCV? I can get the exact fuel trims but I’m they were high, like 20s 30s

 

I’m pretty sure there is a leak where the pcv valve connects. When I fiddle with it, it lets out more air and it runs rougher, And when I shut off the engine it sounds like air is coming from there ??
