car vibrates under accelaratiom

Plugs are a good idea, but we always run into other situations. Other considerations are motor mounts, cv axles, etc. Is the engine light on? A drivetrain situation will need to be driven by a mechanic or a car savy friend to determine the fault, otherwise we are just guessing from things we see, but without driving your car all we can do is suggest.

thanks ProfessorG, had it checked out was told either half shaft or wheel bearing

Glad you found it. You're welcome.
