I have had my 1994 DX Corolla 5 speed (now 90k miles) since September last year and it is PERFECT except that it vibrates the most on RPM 1200. It does vibrate on higher RPMS too.
At idle it is very quiet and smooth.
This is when the car is parked in neutral so there is no transmission issue to my knowledge.
The car's engine is original and very sharp. Could it be the engine?
The previous owner put a clutch plate in it that was defective. I had that fixed and that took away a lot of vibration 4 months ago but some vibration STAYED.
The motor mounts (according to mechanics) were fine as I got checked a few months ago.
I decided (yesterday) to take the car to a level of perfection only a new car would have. I decided to ask the dealer to look into the minor vibration in my car and check the motor mounts (yesterday)
They looked at it and said there was NOTHING wrong. I came to pick the car up and it vibrated like crazy. It has been a nightmare since last night. I took the car back to the dealer this morning and told them to ask the mechanic to track his steps and see what he might have TOUCHED down there that increased the vibration.
IF they don't figure nothing out, I am going to take it upon myself and start chaning all its motor mounts one by one (one per month) for the next 6 months or so. It will cost me around 600 dollars but there is absolutely nothing else wrong with the car other than the D*** vibration.
I hate it when they say, "Oh it is an old car"... WELL.. whatever wore out, can be fixed. Find out and fix it. Don't give me the old car crap.
I am sick of this vibration and felt like crying like a little girl yesterday as I was very upset.
DESCRIPTION OF THE VIBRATION.........
The car does not SHAKE or anything. It feels like the engine is in direct contact with the body of the car so any vibration in the engine is directly getting transferred to the car's body and then to my seat and body. Because of vibration, different parts of the car vibrate.. i.e... the windshield washer box, the dash console or any part that is not extremely tight.
When I go over a hill.. right when I start coming down.. it is ecstasy because the vibration goes away..
I got a call from the dealer a few mins ago and they said that one of the motor mount BOLTS were loose and the mechanic TIGHTENED it and as a result I might have seen more vibration.. That motor mount is loosened now again and I am picking up the car..
He said that the motor mount costs 290 dollars and that might not really fix the problem.
I am going to pick the car now.....
DOES NOT HAVE "MOTOR MOUNTS" WRITTEN ALL OVER IT ???????

It is not right.. Just plain not right.
