Having power issue, own the vehicle for long time but never happy with power and engine performance since ever, it’s my third sequoia, had 01 and 03 before but this one seems having not enough power since day one, even it has only 60,000 mile when I got it,
‘starting great, move great from zero speed and run great in normal speed but dose not catch speed enough without pressing too much gas pedal, spark plugs replaced, pcv valve replaced, air filter mass air flow sensor cleaned, brake rotors pads, rear differential oil replaced but nothing worked

Catalytic converters may be clogged. I would also check to see if the fuel system is working properly. Have you cleaned the intake lately?

The torque band of the 4.7s are also high in the revs compared to domestic V8s.

I will check the Catalytic converter temperature with the lesser check and I didn’t check the fuel system or clean the intake,
Since starting is great, cruising around fine but vehicle doesn’t feel happy when press the gas and try to speed up, getting on the ramp or something. It got 125k on it, I never suspect the Catalytic or fuel system.
Help me check the fuel filter please if there is any batter way you would recommend. Thanks

I need to tell you that my recommendation comes from my experience replacing the exhaust on my own truck and the improvement of power from it. I am not basing this on mechanical knowledge.

The symptoms you listed were the same that I experienced with my truck. It started fine and held speed well, but it was a little sleepy getting to speed. After someone stole my cats and had them replaced, the truck was way more responsive. Part of this may be because the computers adjust fuel based on exhaust, so if you fix the exhaust, the fuel delivery will be fixed too.

Since catalytic converters are an expensive part, please test or have a mechanic double check.

I have an 2000 tundra. The DONT have a lot of passing power. But ever since I put a pos-traction rearend. I put 430 gearing . This thing is a beast. Also check and see if your catalytic converter is clogged. That would cause a great power loss.

Yeah, I checked catalytic converter using laser temperature gun and check the blow pressure of the muffler and other basic checks at my level and it seems Cat converters are fine, it has two, I’m considered about the one on driver side little but I need to have it checked by professional I believe.
