maybe you need to have wheels balanced
We are actually having that same problem with our car and it isn't the tires. We just bought brand new ones had the mounted and balanced and also a front end alignment done on it and it still shakes while driving..
Maybe its your motor mounts.
Yes, either can cause a shake while driving.
You have a fuel injection problem. Have it looked at by a knowledgeable person.
Nope.
Wheel balance may be off...
I don't know you tell me.
Wheels are out of balance
check the upper and lower trail end bushings
lose bolt no seriously its probly your alinement is off
A 350 engine will idle good but cut out and run rough while driving if there is a vacuum leak. This causes too much air to enter the engine under load.
Sounds like wheel imbalance or possibly a bad wheel bearing(s).
It might be a broken motor mount or transmission mount.
