So I have been running a 85 shot on my car for around a year without an issue I only use it occasionally maybe 6 times within the last year . Well my friend wanted me to take him for a ride about three weeks ago and I purged the nitrous through the motor while I was stopped .. The nitrous solenoid stuck open and continued to spray after I let out of the throttle !!! The car stumbled and stalled out after about 10 secs .. Well the car ran fine no issues for about a week and has not thrown a cel or anything now it's starting to stumble at idle . It will idle fine for about 6-7 secs at about 700 rpm then fall to almost a stall.. With the ac on idles right at 1000 and doesnt really vary much.. Does any one have any idea what could be causing this could I have messed up the MAF or throttle body somehow?? Thanks for any help you guys can give..

Could be a sensor as you mentioned, or fouled plugs.

Maybe there's something wrong with the valve, and it's leaking some nitrous when it's not turned on. Just enough to mess things up.

I have replaced plugs and the bottle is out of the car so can't be leaking took it to advanced and it is throwing a random missfire code ... But no cel ??

man try changing those plugs, make sure u keep em a step colder when u replace em, and double check man ive been having issues with advanced saying there iridiums are a step colder and i have to check the serial i cant remember at the moment but ithink it needs to have a 6L in it and they sold me twice ones with 5L in serial. dont qoute me on those numbers but there is a chart you can google or find on here, this is how i found out about it. your plugs are probably not in gap anymore, check them out. maybe regap them, and check that solenoid out make sure its not leaking before messing around with n2o on that sweet vq. take care
