Startup with NGK 9's............?
Anyone notice a "slow" startup after running 9's for a few months. My car starts right up but idles very low...almost like it's not getting gas. This happens for maybe 2-3 seconds then it idles perfectly normal. I am also running rich at the moment with an Unlimited ECU still without an IC and Midpipe....everything else I have. So, do you think my plugs are just a little fouled and it's taking it a few seconds to heat up or burn that gas?? Thanks Guyz !

Well, I pulled my plugs and they are brownish black and seem to be wet with Gas. I'm sure it's gas because it's not greenish and it reeks of a strong smell of gas. I don't remember seeing my plugs that wet with gas before. Does this mean I am running way rich and these 9's are taking a few secs. to burn the gas causing a extremely low idle upon startup (for 2 secs.) ?? Thanks guys.

Hmmm, the only time I saw my plugs like this was when my pressure sensor was bad. When the pressure sensor is bad the computer sends max fuel at all times even at idle. You might check that because even if you were just running rich you shouldn't see any unburned fuel on the plugs.
