Now you guys have me wondering, gonna have to check mine.

Deerhunter4

I would. It's worth an hour of time of you ask me. Mine idles way better now.

Everyone of us needs to either do this or have it done if your not comfortable doing it. It's looking like its just that simple. I wouldn't trust any of them to be spot on.

I never thought gap would matter much under no load or light load conditions (idle). I guess I thought wrong.

Just got done checking mine, all 6 seemed to be "close" to .035. I made them all the same (didn't take much) and its all back together. Took a little over an hour, partly due to losing a socket in the Bermuda triangle .

Just a brief idle in the driveway seemed smoother, but I imagine that was just me and the fact the 99% humidity may have started to mess with my thought process. We will see if anything changes, though the change was very minimal for each so I am not counting on much.

Yeah I'm checking mine tomorrow. I have an '11 Eco with about 15,500ish miles makes me wonder if they r burning to hot and the gap is widening. Maybe need a better plug. Or I could be wrong I'll also post my findings tomorrow night

BoostedFitz

I thought the same. I figured the only improvement should be high load and boost. Guess I was wrong.

Checked mine, all at 30-32ish. 2012

I think I am going to try this tomorrow.

What size spark plug socket is it?

Whats the consensus on the gap for a 87 perf./tow tune with the possibility of also using a 87 economy and 93 perf./tow tune?

I used a 5/8" plug socket. 8mm to remove the coils.
I think some of the guys with tunes are going down to 0.030
