I have just bought a 01 Prelude and after I got it the check engine light came on. I took it to Honda and it was a Missfire on cylinder 1. They suggested a tune up. I called they guy that sold me the car, which is an hour and a half away and he said he would take care of the bill if I let his guy do the work.

The check engine light comes and goes. I runs fine and idles fine unless it is cold. When it is cold it idles rough and if the light is not on it will come on in a fews seconds. After it warms up it is fine. Anyway I took the car to this machanic that changed the plugs, wires, cap and rotor. When I got in the car he had test drove it so it was warm. It ran fine with no engine light on. When I got in it this morning it idled just as rough as before and them the check engine poped back on. Back to the shop I go. Missfire on cylinder 1 again. The mecanic told me that he would not be able to tell the problem untill the engine is cold again so I had to leave it over night. I drove home in a loaner car (damn Saturn)

Does anyone have any idea what would cause
1. Missfire on the same cylinder every time.
2. Idles rough only when cold. (When the missfire happenes also)
3. blows smoke out of the car.

The car has 74,000 miles on it.

Thanks in advance!
