Contour Enthusiasts Group Archives Forums General Troubleshooting engine is really vibrating

i just noticed that my engine started to really vibrate more then usual, it first started out as just a little "thump" when i was driving at low speed, but then it got worse and when i start the car up it is really vibrating, the car has almost 60 k miles on it and is a 95, i heard that its prob. one of my sparkplugs is not working or somting.l......please help this car is my baby

Mine also is a 95 V6. The engine on mine idles so smooth that you can't tell it is running! This engine idles better than my 2001 Saturn!

It really is hard to say without more info. Could do simple inexpensive changes first. Replace the fuel filter, replace plugs and check old plugs for oil fouling, etc. check vacuum lines to see if they are cracked or broken. Change PVC valve.

Hope this helps you get stated in the right direction!

thanx, tomm, im gonna change the spark plugs and wires so i hope that works, if not then back to shop my baby goes, well thanks again.

Missfire would cause it
Broken motor mount
Intake leak

I bet it's the motor mounts! The ones in my Grandma's 1995 V6 were replaced a few months ago. The engine vibration was only there on slow speeds, then pretty soon it was there all the time and made the engine very noise. Now that they're fixed sounds like new again.
