Hello guys I’m still alive with my famous F150 4.6. I’m crazy I changed MAF and stil same issue. I running around and I don’t what to do. I put $$$$ in this and still same. What I notice better sart and driving when is sunny day and hot

I change fuel filter checked fuel pressure idle 32psi when I drive 40psi new coil pack, new sparks and spark wires,changed used EGR changed DPFE and all vacuum valves two of them, changed MAF and cam sensor, cleaned TB last year, changed intake manifold gasket last year, checked vacuum lines and all PCV , checked brake booster vacuum ,IAT just in case, checked everything around 4x4 and small tank on the of battery and still no power no acceleration

Is possible exhaust muffler?

I bought this truck 3years ago. Was first truck in my life I never had a truck. When I bought I was so happy was pretty much everything OEM. After half year transmission is f.... I rebuilt f transmission after year and half start getting overheating on first start after 5km drive all coolant out. Than I changed IM gasket. Same story again and in few months checking and searching I decide change new water pump and radiator. And overheating is gone. I think was old radiator !! But now is done I changed WP. Old one was OEM and still like new inside no squeezing was like a new. Was hard to remove everything. All that time I think was lack of power and acceleration. I driving few times to Kelowna hard time for Qoquihalla big mouth. Than again last year transmission. First time fuc.. guy they just milk-me. Now I decide fix my truck lots of $$$$ in. No check engine light. And guys just give me a order like MAF sensor is lazy and fuel Trim is +23 when acceleration.
Sorry English is my second language
thx
