My van is a 2003. It was running smoothly until two weeks ago after an oil change at a garage. Right after the oil change, when I stopped at a traffic light, the engine rpm's went up and down between 700 rpm's and 900 rpm's. The drive gear (shift) is on drive. If I shift the driving gear to parking or neutral, the engine would run fine. After fifteen minutes of driving, the symptom would go away. I brought the minivan back to the garage. They said there was a vacuum leak and fixed the problem. However, the problem is still there.
I took the minivan to a Honda dealer. At first a mechanic said that he could not find anything wrong. There was no error code. Then he said the air control valve is bad and replaced it. However, the problem did not go anywhere, even worse. Now, no matter long I drive the minivan, the symptom stays on.
But if I turn the steering wheel to either right or left for some degree while the driving gear (shift) is on drive (of course I put my foot on the brake pedal), then the engine would run smoothly.
What could be wrong?
have the same problem?
