If your only getting the code P0303 and you can feel the missfire?Then I would do a spark test and see if the spark is a nice blue spark on that plug?

Yes the only code is that P0303 the car does not chug.I just notice in the RPMS the missing.
So you don't think it is the coil? Cause we are going to try the coil pack this weekend.

Today I went and filled up the car with gas and now the service engine light is off? Doesn't feel like misfire anymore but there still smoke coming from under the hood when I got home from a 70km drive.? Now what? Should we change the coil anyways?

If its running good now I really doubt you have a bad coil. Where's the smoke coming from?
