code 43, not lately!

Hi

Well, this is the LONGEST I have EVER gone without a code 43. No misfire in
over a year now. (I hope I don't ruin things by bragging about it....
)

I have read a lot of posts about bad valve springs, and I know that could
still be part of the problem. I noticed the last time that I had maybe a
half-quart or more of too much oil. So, I decided to start changing my oil
myself. My local quick-change garage wasn't giving the oil enough time to
drain, and would just fill back up with 6 quarts and get me out in 10
minutes or less. I have been making sure that I put no more than 6 quarts
back (sometime just 5 and 1/2), and I can say that the 4.0L I6 seems to run
much better.
So, I have seen other posts here about this. If you have trouble with
misfires, try checking the oil level. Who knows.
What does the group think?
