The weather is very nice with temps in the low 60s. Oil temps barely touch 200F from a whole day of driving. I was leaving from volleyball practice, started the car, and the it felt very good. Acceleration is smooth and quick without requiring much throttle input. After driving for awhile I started to bog the car more than usual as if I'm not giving enough gas when engaging 1st. I even killed it going in reverse. I made a left turn and tried to give it more gas and let it rev past 4k, but the car felt like it was struggling to move. The car felt like it had the power of a 4cy sedan going up a slope, and the acceleration was pitifully slow. Throttle response is fine. I can inch back and forth on it, and it responds immediately. It just has no power to move.

Therefore, I believe the engine is losing power after awhile regardless of oil temps. It idles fine, revs fine, but it literally has no power. The car felt heavier than usual. Turn the car off, let it cool for a bit, and the power comes back on tap for several minutes of driving before losing power again.

This explains the phenomenon of why a Hummer, Corolla, and even a G37 can casually out accelerate me through an intersection even if I gave it 50% throttle.
