Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Normally when you have a misfire the engine light will flash. If it's raining or wet where you are you may need a new distributor cap and rotor along with a set of spark plug wires. This is usually the case when the light is actually flashing. It does mean there is a misfire and that is why it's shaking. At highway speeds it is likely still happening just not as bad at the higher rpms, its not as noticeable.
