hey guys, have a 570 here that acts like its running out of fuel at wide open. If you stab the throttle it will run up to about 7400rpm real quick, then fall back to about 4500 and from there it will fluctuate back and forth from4500 to about 6500 and seems to stuggle to run.. if you creep into the throttle real slow it seems to do a little bit better. ITs not throwing any codes so of course I suspected fuel pressure. I checked the fuel pressure right out of the tank and im getting 50psi so that’s not the issue. This thing will start as soon as you hit the key and run all day long if you just casually cruise. THis issue started all at once completely out of nowhere the guy says…….any ideas? TPS would throw a code wouldn’t it?
