There is this Nissan Altima GXE 2000 (mileage 61000, automatic) I am considering to buy. The problem is, while idle, (like at the redlights or stopsigns) it shakes, but as soon as you press the gas pedal, shaking disappears. What do you think might be wrong? and how much it costs to fix? one mechanic told me that its normal in 4-cylinder cars! but the shaking seems too much to be normal. anything else you suggest me to check before buying?
I also noticed some oil leakage along the cylinder ridges.
