HAVE A STRONG VIBRATION IN FRONT RIGHT OF ENGINE THAT INCREASES WITH RPM AS I GAS IT.

1994 Toyota Celica • 190,000 miles

Motor mounts have been changed. No effect on fixing vibration.

Celica GT: I had the timing belt done at about 150k. Car now has 190K.
Car Idle is smooth. But gas it and it is a very noticeable vibration.

has new plugs. No change in vibration.

I wonder if it could be the TENSIONER? How do I know for sure?
Cost? Is this difficult to do IF NEEDED?

Could it be a HARMONIC BALANCER? DOES the Celica GT have one?
Where is it? Cost? What is involved in this repair?

I banged on catalytic converter and no sound of any shaking of pieces
seems to be evident. Is there another way to check it?

Could it be something with the ac unit which runs off the main belts?

Got any ideas on how to ISOLATE the vibration?

The harmonic balancer is mounted to the engine's crank shaft. Yes, it could be the problem. Also, remove the serp belt to see if the vibration goes away. If it does, it could be one of the belt driven accessories. NOTE: Only run the engine long enough to determine if the vibration is gone. Damage could occurr if you run it more than a few seconds with the belt off.
