i dont know why its doing that. and it changes gears at 3000 RPM's and doesnt let the gears out smoothly.

 

what type of milage are you getting, and has the engine ever been tuned? what is your current milage, and what maintenance has been performed on it.

 

i think im gettin a little under 20 miles per gallon cuz my car takes 23 gallons and it lasts me a week. Before i brought it with me my dad did the tune up. and currently i have around 165,000 miles on it. the only maintenance that has been done has to the oil change from what i know.

 

i have exactly the same problem. i dont know why is it happening. what is the round of mileage you are getting.that can be helpful to answer your query.
