The car has a strong shuddering/vibration whenever it is idle/traffic light.

It happens at both neutral/engaged gear.

The shudder is quite bad as you can see the steering wheel shakes violently up and down. Bad as it is, I can feel my seat is shaking as well.

I can seems to reduce the shudder a bit whenever i turn off the AC.

Sorry for the late reply.

Clean the throttle body, check and clean the idle air system. Give it a tune-up. Check for applicable trouble codes. Your obd1, you should be able to check some codes, yourself. To check codes, you use a jumper wire between the A & B terminals at the datalink connector. Turn key just till the dash lites come on, no further, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
