ok, changed the selenoid for the front mount and no improvement , did the throttle body and idle cleaning but no improvement. I had it on a lift and put preasure on the front pipe by the mesh flex and it seemed to go away but the rest of the exhaust vibrates still. also if you listen to the exhaust coming out of the rear mufler it also sounds strange. i know it sounds funny to say it sounds strange but i worked on cars for 28 years and it just doesnt sound right. maybe something is clogged in the exhaust. also i had the dealer change the timming belt last may and there is a a sound comming from the plastic timing covers but almost like metal on metal rubbing together., maybe something in the timing belt area is giving me this vibration problem.
Anyone know a good lexus mechanic in bergen county new jersey area ?
