I know this is not a new post, but, I think I may have finally fixed the dreaded vibration
while in gear with the ac on.
Just replaced the tensioner and serp belt today.
Hey, what do you know, no squeak, squall, rattle,bump, or unneccessary vibe.
Considering everything else that has been changed it's hard to say which part
contributed the most to the problem.
four motor mounts
idler pulley
tensioner pulley
spark plugs
plug wires
iac valve
air filter
2 serpentine belts
I know this is the long way around, but after reading all the posts I didn't know where to
start.
Good luck to everybody else!!
