Anyone know if I'm running lean or not? Or it's normal.
The tip looks greenish or something
This is a stock b18b1 with intake exhaust and headers.
Also got wideband installed afr at idle 13.9-14.9
Cruising 13-14s
WOT 13.0-13.4

 

looks normal to me some oil build up at the thread base but the actual tip looks fine.

 

X2, plug looks OK, but you need a new V/C gasket set, the spark plug tube Orings are shot. 94

 

x3 the greenish yellow tint comes from sulfur they use in fuel additives.

 

You want a solid, black fuel ring, which you have, your fueling is good, your timing mark looks good too, typically you want your timing mark, around the 90 degree bend..which yours is.. you can see the color change, from the front of the tip to the bottom, the darker grayish part is your timing mark.

 

Thanks ddtech for the good info, what I needed and also for the rest of you guys.
Feeling confident I street tuned this myself. Took awhile to do though.

 

How can you see the fuel ring from all the oil on the plug? Besides the plug would need cut apart to see the fuel ring at the base.

OP: You are running lean, hope you don't melt anything.

 

Good info. I like to learn a lil more on spark plug reading.
