Ok here is the problem. I have a 2003 honda civic ex with a 5 spd manual with the 1.7. It is a 2 door. The car has 80,000 miles on it. The car upon startup idles rough. It then drives fine. Other times I will start it up, put it in first gear, turn on the air and then start driving. What happens is I will be pressing on the gas pedal and then all of a sudden the car will stop moving the rpms will drop and the car will not move. I even have my foot all the way on the throttle but it won't move. At first i thought it was an ac problem but then i turned off the ac the other day and it still happened. There is no check engine light on and honda can't find the problem. Help!!
