I have a Noszle nitrous system in my car and it works perfectly fine EXCEPT for when I spray it down the 1/4 it works perfectly fine then it decides to stall like the motor is being flooded with fuel when I let off the gas, the plugs show a good mixture not lean/rich or any sign of detanation, then the car will not turn on for a couple of secands unless I blip the throttle a bit, I can't figure out why it is doing this because the car drives perfectly fine on the motor and on the spray (except when the nitrous turns off), then I was thinking maybe it is a dying TPS sensor but my vafc is showing that it is working perfecly fine as well. Any tips/help would be greatly appreciated

 

maybe sticking fuel solenoid? is there a way to test it?

 

my friend runs nitrous, this happened to him before, but what caused it was his spark plugs.. the head of the spark plugs were all messed up, he changed it, and it ran fine.. if you already checked your plugs.. i can't help ya

 

yep changed the plugs and still happening

 

ended up being a arking wire, fixed now
