a small update on the matter, I started the car this morning to see how it acts while idling and no matter if it's in gear or not, the whole car is vibrating/shaking, and I don't think other transmission parts could be responsible for that. Or could they?
Is this happening when the car is stationary?? with the engine running
If the engine is vibrating and shaking could be a faulty injector or valves causing a misfire.
