Operation BirdBOMB

I sprayed a 150 hp NX wet kit for the first time yesterday. It definitely did not go well. I floored it from 50mph roll, then hit the switch, and the car fell on its face...then started to pull a little. It honestly felt slower than it normally runs on motor. My scanmaster read 000 for 02 millivolts, so I immediately got out of the spray. I only sprayed for 3 or 4 seconds at absolute most.

Today, the car runs like complete $hit. It will turn on, hold an idle, the coolant temp is solid ~200*, it doesn't smoke, and that's about all the car has going for it right now. I have about 5* of KR at half throttle. It drives somewhat ok if I try to drive it real easy, but for some reason when I let off the gas and coast, the 02 sensors don't cycle. They get stuck around 001-020mv and the car studders, bogs, bucks, whatever. It isn't fun.

I had it scanned with a tech2 today...misfires were high on all cylinders, and off the charts on cyl 5. I haven't checked the plugs yet, but I will changed them all tomorrow. I'd check them now but I'm not at all sober.

What I'm looking for with this post is for somebody to reassure me that I just screwed the plugs up really bad, and that the motor is fine. Somebody please tell me that my motor is ok. I don't have the cash to rebuild it right now. Thanks.

My best guess would be melted or damaged plugs.

You should also do a compression test and leakdown test.

Were u running the 150 shot on the stock plugs? Is it a wet kit? It's just a plug or maybe ALL the plugs. Get you a set of NGKTR6'S and put them in. It'll run fine. You jus t fried a few plugs. Nitrous rule number 1 for the LS1 cars....Never run the juice on the stock plugs! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

plugs could be the problem an o2 reading of 020mv shows a lean problem also a friend who is an asa crewchief says that you need the coil packs with the heat sink fins on top

If only fuel sprayed the car would bog like crazy and black smoke would shoot behind you like James Bond.

Car might run crappy afterwards from getting so much fuel on the spark plugs.

I agree with most of these suggestions, If yuo've got stock plugs, swap to the NGK TR6's. Also, with the car turned OF make sure the N20 solonoid is working properly, bottle is filled, etc. etc., it sounds like when you hit the switch you got only fuel and no N20. INSTAFOUL! All the plugs would be gone byebye. Swap them and let us know.

Pull the plugs and check them out. If they are melted you might be in trouble. Just fouled and you are probably ok. You definitely dont need heat sink fins on the coils <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
