All coils have power. no check engine light except p0300. no ticking noise from lifters. Running like it's bogging down like no fuel ...
Try hooking up a fuel pressure gauge to eliminate possible issues with your fuel pump and lines. If pressure is within specs, then you can proceed checking the injector connectors for power and signals. A scan tool will be helpful in diagnosing coil and injector problems. good luck ??
You need a hand held engine scanner to see what the sensors are telling the engine computer. This is how mechanics today diagnose engine troubles. One thing you could check is if the fuel pump is putting out the correct fuel pressure at the injectors.
Testimonial: "Thanks, I have done all of that. Looking for something I might have missed. Checked fire to all coils. good. fuel pressure. good. It's like it's in afm"

check exhaust back pressure at the headers.should be no more than 6 psi..check fuel cap for venting the fuel tank.some caps dont let air in

How about a defective fuel pressure regulator, buy a fuel pressure test gauage from Autozone and test the fuel pressure under a load and at idle..
A leaking exhaust manifold could make a ticking noise. So could a lifter or valve. The exhaust noise would be louder under load.
If the carb is running too lean, or you have a vac leak, the lean fuel mixture could make the exhaust leak worse, and cause the loss of power.
Testimonial: "Thank you for your help. I was on the right track, and your answer makes sense. I have been running heavy loads in it lately. Have some work to do!"

the slight tick is a valve that needs adjusted-run it by autozone advanced or pep boys and get a free diagnois-you might put a coil pack in it-they do go bad-also EGR valve. They can help you at any of those places-Cheers Denny
