I decided to wash my engine the other day and I may have soaked it a little too much. I started it up the next day after cleaning the engine and noticed the car is "chugging" bit from idle to about 2500rpm. Almost feels like it is starving for fuel at different rpm's. I had a new fuel pump put in a few weeks ago so I know that its not the pump or ccrm. Not only is it running very choppy now but the "service engine soon" light is now on. But sometimes it flashes. I dont have a code machine but any ideas on what I should check??
