After Changing my CPS I noticed a loud chirping noise on start up for a few seconds, (10-20), and then it would go away. Also makes it when I am shifting but only when I am at top end of RPM. At first I thought too tight a belt and that it would loosen later and stop but not the case. Kinda sounds like a bearing going bad. Any Suggestions? Also the warmer the engine the less it does it. Thanks. 1990 SHO MTX W/ 100K miles
