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.
It is possible that your oxygen sensor needs to be replaced.
have it checked out, thats the most common reason the engine light comes on.
P0128 error means thermostat stuck open, replace it.
then reset computer with scanner, lights and codes should go away.
Before you reset it you need to find out what set it. If you don't have a code scanner take it to Autozone, they will do it for free and give you printout of the fault codes.
You can buy a hand scan tool and turn it off. If you can't get a scan tool, you can remove one of the battery cables and wait for 10 mins before hooking it back up. But keep in mind that you need to reset the radio and clock
