Shakes or Wobbles problem
1994 Other Chevrolet Models V8 Automatic

When you start this Step Van the engine shakes. The #6 and #8 spark plugs aren't firing and are wet with gasoline. The other ones are fine.

Are they wet because there is no fire? Have you verified spark on those 2 cylinders. If you have spark, I would check the compression, It wouldn't hurt to do a complete compression check. If they are low on compression, try a little oil in the cylinders and repeat the compression check. If you still don't get compression out of 6 and 8, you have a mechanical engine problem, broken valve springs, worn cam lobes, leaking head gasket between cylinders, piston/ring concern, to name a few.
