Eco spark plug gap

Checked mine this weekend. All were between .035 and .040. I gapped them all down to .030. I can say that the idle is smoother but haven't had the shudder in a while so I don't know if it will help that. I do want to mention that the ceramic on one of the plugs was cracked pretty bad. I don't know what effect this may have been having but I got a new one to replace it.

I can absolutely feel a difference. I got on it going to work this morning with a corvette on my butt and let's say he seemed to be struggling to keep up.

I had a misfire in 3rd gear if I push it or hammer it. Have not drove it about 25 miles sense but soon far no more misfire. Idle is good now.

Checked mine tonight. All six were .042 Gapped them all to .032 Runs better all around. Idles smooth as glass now. I didn't think it was all that bad before but, seeing the difference, I'm pleased.
