2007 Ford F150 5.4 engine. Engine light on?

Won't pass smog.engine light on. I have an evap code P0446: Evaporative Emission system vent control circuit. I also had a misfire on #4 cylinder. I swapped #4 coil for #3 positions. Now, I do not get a blinking engine light; yet, my truck won't even run up a hill, it starts bogging down. And now getting no misfire codes. What could be the problem. I'm pulling my hair out at this point.

I'm using Innova 3120e OBD II

Thank you in advance for any light shed on this. I would be greatful for any help at this point.

1979 ford f150 302 v8 problems! Crank no start?

My 79 ford has a 302 small block ford, I had to replace the starter in my truck a week ago due too it wasn't kicking back. But before I put the new one on I would start the truck to let it warm up due too it was below 20 degrees. But the truck started to have problems starting it would crank and crank. Then I would dump some gas in the carb and it would crank for a bit then slowly start to fire up. But other I replaced the old starter and had the new one I went to go start the truck and a it did was crank. I poured gas in the carb, and it would just crank and crank. I replaced the coil and I replaced the plug wires. And I got spark and fuel and good compression but still not firing over. Could have something went bad? Or something? I beer disconnected any wires or touch the engine while changing the starters

Is the new Ford F150 a good truck?

I'm in the market for a vehicle. However I want to get a truck with a real engine. Cylinders being shut off has never worked for anyone I know. With that being noted, Ford looks the best. Aluminum body though?
