Hi Scotty! Great show, sir! I have an 07 Tundra that bucks and stumbles like a 3 legged mule when under light throttle load. I have also noticed that it has been burning oil as of late. I've replaced the PCV valve, spark plugs, coils, camshaft sensor B on banks 1 and 2, and the crankshaft sensor. At times it will run great, and at others not so much. Usually when I drive aggressively the bucking begins and then the engine will start running lean and trying to stall under light throttle load. I took it to a Toyota dealership Thursday and they found that the oil filter housing was damaged and identified that as the culprit. After replacement the truck ran great for about 10 miles of city driving. Once I got on the interstate and hammered down the accelerator the rodeo began. My check engine light is on and the reason is a faulty power steering pressure switch. Note that the check engine light has been on for about 40,000 miles now due to the PS pressure switch code and has ran just fine. What do you think? Pressure switch the culprit?

Honest opinion...Does it sound like a leaking intake manifold gasket to you? If so, I can replace it. Just need a proper diagnosis as no one, Toyota techs included, can figure it out. It runs great at low idle when first starting. When I take off down the road the hesitation begins, and before long I'm bucking like Lane Frost on Red Rock. When I stop, I disconnect the battery terminal cables for 10 minutes, reconnect and then she runs good again for another 10 miles before the process begins again. Thank you.
