My car vibrates when I start the car in the morning and stops when the car is warmed for a few seconds. Initially through out the day I wont feel the vibration until the next morning. Now on driving the vibration continues and is worse when I stop moving with drive on.

what could be the problem?

I would change the plugs if they have not been changed, and put a can of SeaFoam in the tank.

It could also be a weak mount, or possibly a sticking convertor lockup solenoid.

But I would start with plugs and Seafoam, use only NGK or Denso iridium plugs.

Thank you very much for your answer. I think your right cos I found out that the 3rd plug was completely loose and was tightened. The vibration has reduced tremendously but I think I should just change all. Ill try the seaform option too.

You are welcome.

If the car sits in garage for more than a month, gasoline will deteriorate and break down causing varnish to form. This can cause many problems.

SeaFoam or fuel stabilizers (such as Stabil) will counteract this problem, keeping gas fresh for over a year.

The loose plug will cause problems, replace and use anti-sieze (small dab of it) on plug threads to prevent galling, also use dielectric grease on plug wire connections, this will seal plug and keep moisture out of plugs. Torque plugs to proper ft. Lbs. And again use Denso or NGK iridium plugs on this engine.
