Have vehicle scanned to determine the problem
Most likely it is a dirty or malunctioning oxygen sensor located on the manifold.

If the check engine line is flashing then that means there is a real problem and you should have it looked at, But if the light is on and NOT flashing the it is most likely a problem with the emmisions system and most likely an oxygen sensor.
The Service Engine or Check Engine light comes on when the ECU has detected a problem with the emissions system. Do not ignore this light even if the engine seems to be running fine. Failure to repair this can cause damage to the catalytic converter especially if the vehicle is not running good or using excess fuel.
I washed my car at the car wash, then I washed the engine with engine/tire cleaner with the engine running, since then my check engine light has been on. Sometimes it blinks fast, goes off and then comes back on steadily. The engine sounds like sputter, misfire, rough sound from the tailpipe. The entire engine seems to be running fine, no shaking or bouncing, just running normal. What is the problem? Thanks for your help.
