When is the last time you Removed and Cleaned the Throttle Body? Sounds like it's Clogged Up, Injectors Need Cleaning You're Replacing the Fuel Filter (Should be done every 8 to 14 Months). How are the RPMs when the car is in Neutral? You may have a fuel or plug wire or spark plug bad if there is an engine miss.or bad catalytic converter..
