Q: spark plugs on 2000 Ford F-150 Lightning

We have changed MAF, spark plugs and wires, O2 sensors, fuel filter and tried fuel injector cleaner. When you start it you have to hit the gas constantly or it will stall, you can't stop at res lights or stop signs without holding the brake and keeps the gas on also or it will stall. It starts right back up after it stalls. It runs fine once you get moving, it has some loss of power. What seems to make the problem better or worse? Stopping or driving at low speeds How long have you had this problem? A few weeks

occurs everytime it's started. have changed throttle body, crankshaft sensor, camshaft sensor, egr valve, computer, all 16 spark plugs, had aftermarket muffler put on and problem happened not long after. What seems to make the problem better or worse? Nothing How long have you had this problem? 4 mths

I have no spark. It was running fine, shut it down for about an hour and suddenly no spark to plugs. Check the coil no spark there. Changed the coil and still nothing. Turns over just fine? Where do I go from here? What seems to make the problem better or worse? Also has new plugs and wires
