on cold start my car has an excessive amount of vibration, as my car begins to warm up, the vibration goes away during idle, but returns with a vengence around 2k RPM and onword throughout power band. i was thinking maybe Harmonic balancer? or maybe motor mounts, but the thing is the mounts dont move what so ever while the motor is revved, is there anyone that can shed some light on this topic for me?

i'd recomend a obdii test, if you are obdii.

its a 5th gen GTS celica which is non- OBD2, any other suggestions

You can still run a scan tool on it, just go find a place that has the OBD1 connectors.

might be a air sensor or maybe the IAC.

is it the GT or ST?

its a Gt-s,the CEL is not on, so an obd1 code should not be present.
