The error code will give you an explanation. The codes are tabulated by BOSCH in a massive code table.

OBD-II Trouble Code: P0172 System Too Rich (Bank 1)

It could be air-mass. Vacuum leak. Fuel pressure. Exhaust leak.

Easy options include vacuum pressure test and fuel filter. Expensive options are air-mass sensor.

But the vibration tells me you could also have a cracked exhaust manifold. The loss of exhaust pressure can do that. But it has a particular sound and the air inside of the cabin stinks of the exhaust.

Did you lose much power and did you stall ?

hi i think i didn't lost too much power it runs normal but when i lock accletor padle there may loose power 10% to 15% she was pulling me back to stick with seat, not now may ( may be i express my experiance or not)
