SOURCE: service engine light
you have to have the code read at a garage equiped with scanner to retrieve and eventually erase the code your car is running on safe mode not the best setup

I have the same car and if the gas cap is loos for any reason the service engine light will come on so check that. If it is it will turn off in a few days after you tighten it.

it means you have trouble codes in engine or trans controller..any performance difference of your vehicle?you need to have vehicle scanned to determine what is going on..let me know

this light means that a fault has occured in the electronic engine and/or emission control system, any time this light is turned on there is a trouble code set into the memory of the Powertrain control module, PCM for short, there are over 200 poss problems that turn this light on.

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.
