Get somebody to read the codes. there is a speed sensor that has to be replace in your vehicle and that is why the servie engine soon light come on because it is aware of the problem when the speed is jumping around.

Sometimes it comes on when you have to replace your air filter due to it being dirty. It will also come on when the gas cap is not tightened or needs to be replaced.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

The speedometer signal comes from the transmission computer via the output speed sensor on the front of the transmission case. The tachometer signal comes from the engine computer via the crankshaft position sensor on the rear of the bell housing.
