Tahoe tips?

[Tahoe933]

I just got my Tahoe. Changed oil and all filters. Plugs look a bit nasty. What is everyone using for plugs? Do you stick with stock range and gap? Mike

I know that my problem was isolated, but heads up!

I noticed arough-run situation going up long hills, especially towing. After I got settled in my new area, I did a tune up and found the 5 and 7 cylinders had bad plugs. #7 only had 75lbs of compression. I took it to the Chevy dealer and they gave me a new long block. This was at 62k miles and I bought the extended warranty.

I've never heard of another 350 having a problem like this, but thought you might want to know.
