I have a Iswara MT (2010 I think). While driving, when I let go of the accelerator, feels like the something (maybe the engine) wobbles. When I press the accelerator again, something wobble again. During this 'wobblingng' the gear stick also shakes. I'm sorry if the information is vague, but I have no idea how to describe it.

This doesn't happen when the car is stationary.

If my manual gear shift is wobbly (front to back), is that something o can tighten myself or a visit to a workshop of needed?

My rpm meter (left one) has been misbehaving for years. Where the needle sometimes works sometimes not. And the backlighting sometimes works and sometimes not. I did verify that the bulbs are working, by changing the bulbs with other meters bulb.

Looking at Shopee, I could not figure out which to buy. The price varies too much for me to make a judgement. Anyone can suggest which shop or listing to buy? I'm not fixated on Shopee. I can use Lazada or others as well.
