[QUOTE="Ade, post: 166001, member: 95"] Vibration...ask me dude....I'm having the constant same ole' problem... A few questions: 1. Does you engine hunt during idling? (ie: sometimes the rpm goes up and down) 2. The vibration is intermittent but almost certainly frequent enough? 3. Do you drive your car like a sissy? If you answer yes to the above, the main culprits of vibration is always attributed to: 1. (Major) Ignition coil failures - Make sure you have the BOSCH ones. 2. (Major) Hose on the manifold - change that if you have not done so. 3. (Minor) What engine oil are you using - I'm using Castrol Edge 5W 40. 4. (Minor) Fuel filter due for change? 5. (Major) Engine mounting changed? 6. (Major) Dirty valve - Decarb you car. A valvetronic do not have throttle nor idle valve. This will eventually cause vibration. Rev your car once a while....this will help...redline it! [/QUOTE]
