I have a 2003 honda civic auto & 2 weeks ago the maint reqd light startrd flashing but didnt stay illuminated and abt a week ago it now stays on whem i start the car and i noticed a vibration when i start the car but it would always stop once i put the car i drive and took off. Tonite the vibration came back while at a red light omce the car gets passed 40 mph there is no vibration but at lower speeds its vibrating and spuddering. I am past my oil change mileage, but little to no oil loss. What could this vibration be?

 

your maintenance light has nothing to do with anything,that just reminds you you need a oil change or regular maintenance, it comes on automatically every couple thousand miles. it tells you how to turn it off in the manual. the vibrating is most likely bad motor mount bushings among other things. check the motor mounts.
