Recentley I was driving my 02 zo6 and i punched it in 1st gear, when i shifted to 3rd, the motor kind of stopped for a second and then accelerated like normal. Traction control WAS off. When I got down to speed (10-15mph), the car sort of bogged and started to shake heavily. I pulled over and thats when I heard a loud "click click click click" coming from under the car near the motor. I pulled up my codes and there was a "p0300 h c" random misfire code. I checked the clutch and everything looks ok. I switched my spark plugs and wires around, also gapped the spark plugs without success. A local shop (corvette experience) said it sounded like broken lifters. I also checked my valve springs and none are broken. The ticking noise gets louder and faster when engine rpm increases. I will attach a short sound clip from under the car soon so please listen and let me know what you guys think it is. Any input will be appreciated! thanks!
