Why does my car Vibrate when I accelerate?
when I put the car in drive and accelerate it starts to vibrate badly. after I pick up speed it seems to get better
No. It's your motor mount. Focus motor mounts going bad is common. I thought my daughter's exhaust was just loud in her car....I then realized it was the motor mount, replaced it, and it took care of the problem. If you are a do-it-yourselfer, this was not a big deal when I did her 2006 Focus ZX3. The main thing to be aware of is type of motor mount you buy at the parts store. I bought the "insert" and reused the metal housing...which worked fine but is a bit of work to put the insert in and bend the metal tab. The insert costs about $50. If you buy the entire motor mount, which would be easier to replace (pull the old one out, put the new one in) the entire unit costs about $110 I think. YouTube has videos.
Check your fuel injectors, have them cleaned, that should help, also check the spark plugs are in good shape...

It could be your bearings.
i have a2007 ford focus 1.6 si hatchback and when i take off from start the car vibrates or shudders but once i engage into 2nd gear the car goes well thereafter, this only happens when i take off from 1 st gear. my mechanic told me it could be the flywheel.
My guess, which I will substantiate this week, is a worn inner or outer cv joint on the front axle. The driver's door mirror glass vibrates on mine, so I'll concentrate on the left side . Reman axle from NAPA inexpensive, so would replace the axle assembly.
