Gap and Change spark plugs in 98 Monte

[Awilli]

I have a 98 Monte 3.1. Anyone know what the plugs should be gapped to and whats the best way to get at the rear plugs.

Unbolt the dog bone front upper mounts and rock the engine forward, use one of the bolts thru the lt bracket access hole to hold the engine in that position. Gap is .060, check your emissions label or owners' manual.. Use oe type AC plats or iridiums.

Bosch platinums are not a good choice. Research the forums and you will see where they don't play well in GM engines.

Quality on those puppies went away years ago.

No problem. Stick with AC-Delco or Autolite Double Platinums. Excellent quality and longevity.
