Hello: Have you recently had any work done to it ? It may need a tune up.That includes spark plugs, spark plug wires, and a distributor cap, and (rotor if applicable).You may have a bad or cracked spark plug wire causing the spark to jump once in awhile.

Service engine soon light is flashing


When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.

Ex. P0401 means there is misfire on cylinder number 1

P0400 is a random misfire detected.

If you take it to an Advance or Autozone they will usually scan if for free.

By the way, if you used cheap plugs instead of platinum plugs that could do it too.

Hope this helps.

Nissan Sentra "Service Engine Soon" and uncontrolable shaking.


I had the same problem. It was the intake gasket, very common in this model. A $12.00 gasket - Nissan wanted $1000.00 to install it. I got it done for $327.00 - engine light still remains on but car drives just fine.
