Being a 4.6L NPI cougar owner. I request a little bit of help.

My cat has developed a bit of a cough. Like asthema, really acts up under stress. In this case, under load. It has a steady back fire under WOT, and 40%+ throttle it has a spuratic back fire.

Checked the plugs, they look good. All wires are seated properly. Runing Fuel Injector cleaner right now.


Any other suggestions? Possibilitys? Would be apperciated. Thanks in advance.
