could it be the wheel alignment? or uneven wear on the tires. What speeds does this start at? Did you hit a really big bump or something?

Do you mean shaking and shuddering as when driving, or the engine is hasitating?

no, it is in the engine...it is so rough running it seems like its gonna fall out

something with the engine is definately it...it does it from the time the car starts until its been driven awhile...does not do this every time i drive but is becoming more frequent...car has 48,000 miles

There are a few simple items that can be checked before anything else:

If you havent done a tune-up lately this is the basic list:
- spark plugs
- have mechanic test the spark plug wires
- replace fuel filter
- check vacuum lines for cracks
- check the CTS sensor (Coolant Temp Sensor)

Other than that, it may be getting a little bit more complex:
- oxygen sensor, if never replaced (computer depends heavily on that)
- idle-air control valve...to be cleanup
- air temp sensor

Also, your mechanic should pull the codes off the ECM - if there is a problem, the comp will let you know.

Hope this helps

Don't rule out the Cam and Crank Positioning sensors.

my 98 leganza shudderd a bit then not long after blew a crank bearing. I dont know if the bearing was why it was shaking, but it ended up being a $1300 excersize

Check the spark plug wires to see if there connected right. My leganza was shaking also!!!
