Hi there. I recently just got a 97 VTI-R Integra. A few things I noticed with the car.

The tacho seems to jump around. At low speeds it's solid, but 60-100 it's jumping. Do I need a new gauge or is there a problem elsewhere?

My temperature gauge seems to go down the more I drive the car. So when it's hot, the car says it's cold. At first I was afraid I had no coolant, but it has plenty. Could this also be a gauge problem, or as I read on here, maybe it needs a new thermostat.

Also, the biggest issue is the when shifting from 1st to 2nd, if I don't do a super careful clutch release, I feel this vibration and thump kind of noise. If it's an engine mount that needs replacing, is this super labour intensive, or should any shop be able to swap it out without too much hassle?

Thanks all.
