Customer Question

My 1999 Nissan Maxima idles roughly and there seems to be a shake while driving around 20-30 mph. What might be the cause of the rough idle and shake? Are they related?

I am sorry your having this problem

is the check engine light on ?

The check engine light is not on. I don't know if there are any codes set, I can get that looked at. Nothing has been done as of yet to correct the problem. I am trying to figure out what the main causes would be for the issue.
Expert:  Gary replied 7 months ago.

usually if there is a rough idle the issue is usually a vacuum leak or a dead cylinder from a bad spark plug or spark plug wire or injector which would cause the engine to shake when driving if there is a dead cylinder

the odds are it will have misfire codes in the computer and usually finding which cylinder is dead then test that cylinder for spark and fuel

if no codes then usually a basic tune up with wires fixes this issue and sometimes a coil also
