Hello I run a parts sales and repair shop in South Korea. The car I need to repair is f430. The car has some problems, and I'm asking you how to fix it. There's a vibration. When I'm downshifting, there's a feeling that the RPM doesn't change fastly. It seems to be delayed So for now, the parts that I want to change are as follows. 1. Engine mount 216357 (190255) 2. Gearbox Support Bush 237531 3. Auxiliary Belt 235315 4. Alternator Belt 219847 5. Belt Tightening Pulley 226205 6. Belt tensioner 233644 Would it reduce the vibration if I replaced six parts of these? Could you recommend which parts should be replaced to reduce vibration?
First you need to identify the source of the vibration. Start by checking for a broken motor,transaxle,or exhaust system mount.
