SOURCE: Describe your service engine soon light blinking

you have a missfire that is why the light blinks, it also will have a trouble code stored showing which cylinder is causing the problem, but this sounds like a plug or plug wire issue.

SOURCE: My service engine soon light

sounds like a coil misfire, check codes. My astro van did the same thing going uphills. New plug wires are cheap and easy to replace.

Your car is misfiring. You should not drive the vehicle while it is misfiring. If you want to DIY it you can start with you ignition system. Make sure all spark plugs, plug wires, and ignition coils are secure and in good condition.

Service engine soon light after cleaning carb


I too have just had the Service Engine Soon light come on, this week. Hmmm, interesting. We all have 2004 Nissan Sentra's. I too believe the dealers rip people off.

A co-worker asked immediately - How many miles do I have - I answered: 62,528. He said that is a Dealer function...they set it to go off around 60k, so we bring our cars in. Cha-Ching!

Hey, so what if it is not true? Luckily, I have the RECALL NOTICE, so my car goes in today anyway. I will ask them to turn off the SES. If they won't, then I am going to find a service manual, and turn my SES light off myself.
