My friend was driving my car one night, and he decides to treat the my automatic Accord (Stock F22B) as a manual. So, he takes first gear up to 6200 rpm before shifting to second gear. And did the same with the following gears. Well, next morning I start the car and I hear a raddle sound coming from the engine. I pull out of the driveway, and put the car into drive. I'm driving, acceleration was normal, then at 3000 rpm I hear a loud raddling sound come from the engine. So, I'm like :wft: . Then I push the gas to engage V-Tec, and you can hear the raddling sound throughout v-tec. So at 3000 rpm and when in V-tec, I can hear this raddling. If anyone knows whats wrong with my car, please help. Reconsidering a H22A swap for a bike.
