Hmmm...okay. It is a while since I had to deal with spark plugs on any of my cars, I will admit. And I know the computer stuff complicates everything. I did stop changing my own oil because I got tired of dealing with the claustrophobia--I didn't have to put the car up on ramps, but when I crawled under it, the bottom of the engine was touching my chest, so it was only a couple of inches from my nose, and I didn't want to deal with that any more. So now I pay JiffyLube to do it, and it's well worth the relief of the hassle. If it were going to be $400, though, I think I would reconsider.
Hope you get something figured out that will take care of the problem!
Peace, Dawn
