I just noticed this the other day. Very close to 1500 RPMs, I will get a nice vibration that can be felt through the gas pedal. I cant feel it through the brake pedal or the floor, just the gas pedal. It does this whenever I go through that particular RPM, and it doesnt matter what speed or gear I am in, but the vibration is only at the 1500 RPM mark. Any help/insight with this would be greatly appreciated before I break down and take it to the dealer!

Anyone?

Have you looked at the TB for carbon build up?

i have this problem too...esp. when the a/c is on? weird!
mr. bean

now that you mention it sbean, I think it might be when I have the A\C on...I will have to check the next time that I drive the car.

macho_mike21,

i notice it when i have the a/c on and also, i notice it when my blower motor is on the "high" position...kinda annoying b/c i am always wondering if something is wrong with the car ?!??!?

Have any of you looked at the A\C system to see if it rattles? I thought it was a little wierd that it was only at a specific RPM.

Yeah jr, I checked tonight and we have the same problem. I wonder if its the fan coming loose or something of that nature, because it went on for about a second or two after i shut the A\C off. I just wanted to make sure that it wasnt anything serious.
