So, what would your diagnosis be according to these spark plugs.

1,2,3,5,6,7 are running lean. 4 and 8 seem to be running fine.

I just did a little bit of work on the car(about 3 hours worth), and everything seems to be fixed now.

Here are some pictures.

They might be the wrong heat range. I've heard of brand new plugs having the wrong heat range.

I have been getting the CEL coming on all the time saying passenger side is running lean. I changed the O2 sensors, and it does not appear to be coming on any more. O2's were original ones from 1995.
