Sounds like you developed a vacuum leak.Listen for the leak to determine the cause. The check engine light is probably lean codes. P0171 - P0174. You can go to Auto Zone and they will pull the codes for you for free to tell you what codes the computer saw to turn on the light. Look for vacuum lines deterioated or loose on the engine.You can spray carb cleaner to try and locate by when you spray over a vac leak the engine will rev up a little.
