SC400 ruff idle??

[95SC400]

Ok i got sum help off CL but i need to know why its having a ruff idle? when you start its fine,but as it warms up the car will start to vibrate littley not too bad.

You can kinda stop the vibration when you put your foot to the floor on the brake at the stop light,but when you let off a lil itll still vibrate,and you can hear the car sound different when you accelerate.

Help some say its the MAF.

inputs plz

Sounds like your spark plug cables are leaking & shorting out. Try this test:take off the cover that hides the cables then get a spray bottle with water in it. When it begins to get dark in the evening, start the car, then spray the cables with the water. If vthey are leaking, you should see a number of sparks. If so replace the cables. That should take care of your problem.
