After doing wots it sound like the engine coughs or something before it goes to normal idle. Ill see and try if i can upload a video and you guys can tell by looks if its to rich or lean. When car is idleing, under the exhaust it doesnt take very long before i get a big wet spot with oil/fuel. that comes from bein too rich? but if i go any leaner i get temps to 300degrees after half tank. Ive heard the K5.9 run a little hotter than the rest, is it safe to run the engine at 300degrees? That being said my needles are almost flush, HSN 1turn in and LSN is screwed out 1turn from flush. Maybe i got an airleak somewhere, you use green slime on screws sealing airleaks?
