I replaced the spark plugs and oil. Now it has a low idle and cut out when put into gear and press on the gas pedal.

Check to make sure by accident you didn't disconnect any engine vacuum hoses.
Here is a link that explains how to locate them:

How low is the idle speed? Also, is the check engine light staying on when the engine is running? Do you feel any misfire (rough idle) when it is running?
Let me know.
