O2 reading .002??? Now that is LEAN! My car has been running pig rich lately, so I pulled the MAF sensor to check it. It was filthy. I cleaned the sensor element with contact cleaner and low and behold my O2's are a perfect .900mv at WOT now. Before she would bellow black smoke. On another note I installed a digital A/F meter at the same time and had the N2O bottle filled. I went out to see how the O2 meter would read on a short nitrous blast with the TNT 150 shot. I hit it and man the tires immediately cut loose in second gear, wow, looked down and the A/F gauge went from .900 to .002!!!!
I did it one more time very quickly and again the O2 meter dropped to zero! So I blocked the bottle in and bled the N2O. Went out and armed the kit without Nitrous and floored it. The O2 reading stayed a steady .900 I pulled the lines loose from the fuel noid and could not get any fuel when actuated. I'm at work now but I'll have to dig later to determine what went wrong. The kit is about 11/2 years old now and I have not rebuilt the solenoids. I'll determine later if it is the coil or the plunger assembly.

Re: O2 reading .002??? Now that is LEAN! Man!!! That'd scare the **** out of me! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I hope you get that problem down quick, I know how it is to have the kit and can't spray. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />
