#10 of 12 vibration from plastic engine cover by usaicon Dec 24, 2007 (10:13 am)
I have a V6 2006 Buick Lucerne with 24000 miles. I have recently noticed a vibrating noise from the engine compartment that sounds like a hollow plastic box, when the engine is under torque. I removed the black plastic cover that says 3800 and the noise seems to have disappeared. Is there a way to tighten down this cover so it doesn't vibrate?
#11 of 12 07 Buick Lucerne CX problem by mborak Jan 02, 2008 (11:53 am)
When driving at steady speeds I sense periodic subtle resistance and slight tugging resulting in a choppy driving experience instead of smooth. I have taken it into 2 different dealers who have not acknowledged the problem. I drive 80 miles each day and still feel like something is not right. Vehicle has only 2000 miles on it. Any ideas?

Replying to: mborak (Jan 02, 2008 11:53 am) At 2000 miles, the dealer can go over tire pressures and wheel alignment. If the tire pressure recommended is 30, I run 32-33. I like to feel the road. I'm suggesting your push and pull sensation could be tires.   It also could be alignment. They will realign up to 12000 without having to stomp your feet.   The other could be fuel quality? Or a misfire in the plugs in the motor. Try driving in 3rd gear instead of OD which allows the car to shift into 4th gear. How fast are you going when you feel this tugging sensation?
