Need more info like year, make, model and a detailed description of problem.
Depends on where the noise is whats making the noise. Can you be more descriptive of where and what?
Please elaborate your question.
When you can not figure out why your car makes a strange noise, you take it to a mechanic.
you have a bad alternater or belt
Check pLugs and wires and the vibration my be from brake pads or warped rotors
no suv's do not make more noise than a car
Check pLugs and wires and the vibration my be from brake pads or warped rotors
Sounds like a loose alternater belt.
When the idle goes rough, you must idle the plugs. Else the car plugs roughly.
I would get it checked out by a profesional because that one is a hard one to deal with if it doesnt get done right
chech catalyc converter or muffer. check also o2 sensor or egr valve.
Have you checked your Exhaust Muffler and pipes ? Probably the fuel pump
