hi guys,
this morning going to work everything was fine till i got to one stop sign, then all the troubles started. my engine started to buck which caused my whole car vibrate really bad from low rev all the way to high rev, no matter what gear in low rev, if i press on the gas all the way down it chokes and vibrates while increasing speed, but slowly. the muffler at idle sounds like a harley now, or a car with heavy cams. the engine at idle moves dramitacly compared to before. during acceleration you can describe the vibration/sound and gas choking to kinda sound/feel like a tractor lawn mower.

need help, im thinking maybe clogged cat or O2 sensor?

Timing belt tensioner could have come loose....or a sensor somewhere.
