look at the fittings, check the AN fitting in and out of the nitrous selonoid(s)

paste will start to turn brownish, and accumulate dust, tape will be be bright white and obvios cuz the ends will start to fray

w/ the bottle off and car off, arm the system and engage the nitrous, listen to how loud and defined the "click" is after the selonoid opens

 

after the engine was fixedthe solenoids were unhooked and stuff to run the engine awhile before spraying it so ill have to make sure to use paste, thanks for the help guys

 

just an update....paste was used, but as wmrcer said i think it was just a problem with the window switch not being set correctly

 

Are you using a micro switch or a activation switch that works off the TPS?

 

activation switch

 

If it's a micro activation switch that has the little arm that the throttle hits then check it.My nitrous did the exact same thing to me one time and that switch was broken keeping it activated. I had a window switch at the time as well. When I got to the activation point of the window switch the nitrous turned on and even when I let off the gas the micro switch was still activated and it still sprayed the nitrous because the rpms wouldn't drop below the shut off point of the window switch. I had to turn the ignition off. Then I unpluged all the coils and spun the motor over for a solid min. to get all the nitrous out of the motor.
