motor mounts?

[ncsu brandon]

i get shaking from the engine at times...for example i'll be in going into second @ 2000RPM and it's like the thing will shake and then it stops, it's only when i first shift into the gear and then it stops...any ideas?

If your motor mounts are bad there will be a shiny spot on your intake manifold.

and where would the shiny spot be?

The shiny spot would be right in the middle of the intake on the front runner closest to the front of the car. If you do not have a hood liner then you won't have that. Search the posts for testing motor mounts. If you take the pass side tire off and pull the plastic dust cover off you can see the two motor mounts. Look to see that the rubber inserts are still there and not in pieces.

broken mounts will tend to **** the car, not shake. the motormounts in these cars are worthless & will constantly break when used aggresivly. Even the alledged "heavy duty" mounts that some are peddling. hahhh. they still break.

Park the car on a level surface, firmly set the parking brake and, just for safety's sake, chock the rear tires. Raise the hood and start the engine. You will be able to see the intake manifold thru the space at the bottom of the hood. Select first gear and slowly ease out the clutch, try to keep the revs around 1200. Watch the intake manifold, the engine will tilt toward you. It should raise level across the manifold from left-to-right. If the right (passenger) side of the manifold rises excessively (more than and inch) then your front motor mount is torn. Since this is the mount that takes all the abuse when accelerating forward, its the one that's bad most often.

Now, engage reverse and again ease out the clutch, the manifild should tilt away from you. Again, it should be level from side-to-side. If the right side rises up excessively, then the rear motor mount is torn, tho this rarely happens, as this mount is in compression during forward acceleration.

If, during either forward or reverse tests, the left side of the engine rises excessively, then the transaxle-to-subframe mount is torn, this is also a rare occurence.

Another sure sign of a torn front mount is a polished spot on the front-passenger side of the intake manifold, somewhere around the "24v" emblem on the front tank. As the engine rises, it rubs against the hood insulation pad which leaves a mark on the manifold.

Thank you Kevin for a sincere and accurate response to this question.

ok motor mounts are good...

any other ideas???

again it's only if i let the clutch out slowly and at low rpms and then goes away...
