is it running ok? what kind of tranny mount is on it? is it solid poly or stock one with the bridge.

 

a tip for if you think the coils are swapped and numbers don't match, is to look at the coil plate they sit on. it has small numbers showings what coils go to what cylinders.

 

ok so i replaced the plugs ( all the plugs looked exactly the same just some wear but nothing out of the ordinary, i dont have a camera that would take good pics) and wires but it still does it. I tested the Coils with an ohm meter and the coils are fine. i triple checked to make sure all the wires are in the right spots and on tight. I checked the tranny mounts and motor mounts and all are secure and good. It lightly shakes when idle, its when i get in to 2500 and higher it starts to get bad. Im trying to give you the best info i can cuase this is frustrating the hell out of me.

 

I had this shaking at the higher RPMs on my 95 3.4 -- the fix was replacing an electrically dead injector which was intermittently failing over the years evidenced by backfiring in the past.

 

I just decided to take it to a shop. They just got back toe dying it's internal and that they can't do anything about it there.
