Subject: Re: Update On Grace's Rough Idle by bogus on 2018/7/28 20:22:10 I did a tune up on an LS1 about a year ago... that was a learning experience... All of my muscle memory was useless... the plug orientation is just different enough... drat. Then there is the relief... there is a machined surface that the plug rests in... the problem? it requires a thin walled socket to get in between the plug and the elevated portions of the head. A real bitch. What plugs did you use? Wires? When I do mine, I will use KGK or Denso plugs and MSD wires. As for the rough idle still being there, how old are the O2 sensors? I would replace with AC Delco, Denso or NTK (kin to NGK). I need to double check the lifespan of the newer O2s... the old single wire ones were 30k replacements. |
