    My 2008 with 196k has been having lots of engine issues. Rough idle, very noisy acceleration, 38mpg and 2-3 seconds of heavy shuttering when the ICE shuts off at a light. No lights on the dash, air filter is new so I decided to clean the MAF. Took ten minutes using a YouTube tutorial and all symptoms are gone. Plus my MPG is now up to 42-43 over the last 100 miles since cleaning it. Next week I’m gonna clean the throttle bottle to see if it will improve things even more
