The service light means something is wrong with the car and it needs attention now. Get the codes checked and that will tell you what is wrong with it.

SOURCE: 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.

Service engine soon light


A service engine soon light that flashes generally results form an ignition problem with the engine. A service engine soon light that stays on constant results from an emission control system malfunction. A diagnostic scan from the local parts store can determine which emission system is faulty.

If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.

Flashing service engine soon light flashes then shut off


Check engine lights have been used for over 30 years and yet most people do not know what they are used for.
The check engine light tells the driver a problem exists with the performance or emissions of the engine. Not the actual engine itself.
Anytime something happens that could affect emissions or performance, the light comes on and a trouble code is set in the computer memory. The driver then has to have the computer scanned for those codes to know what component to have checked.

Have the car scanned for the code's origin. This could mean that the engine will not work as well as it should, and could cause driveability isues.

A constant service engine soon light means that a hard code exists. A flashing light means that an intermittent code exists, but it could become a hard code very quickly.

When the check engine light flashes, It's not giving out codes. It is telling you that the engine is misfiring on 1 or more cylinders. New plugs and wires might fix your problem.
