Vibration in Lancer 2002

Hello, I have a 2002 Mitsubishi Lancer GLX 1.6. It has a strange vibration when it reaches 2000 rpm. I've already changed the spark plug wires, but the problem persists. If anyone knows what could be causing this, I would appreciate it. Also, if you know where I can find the workshop manual for this model, as I couldn't find it here, that would be great. Thanks.

Does the vibration occur while the car is moving or stopped? And how strong is the vibration, and have they done anything to the engine?

I'm telling you that the vibration happens when it's running, in 2nd and 3rd gear; the clutch was changed 2 months ago.

Hi etrejo.
Check that the tires are properly balanced, as well as the engine and transmission mounts. Good luck.
