Ses Light Problem Under Spray... Im kinda sorta new to the nitrous crowd but i dont know if this is a common problem. While i am sprayin my car (150 wet shot) a SES light starts blinking. It never stays on, just blinks. Im pretty sure I am maxing out my stock fuel pump but i dont know if that would be the problem or not? Anyone had or heard of this problem???
there is a computer shut down for extremely lean conditions. Do you have a wideband or access to one? You need to check your AFR. You can also pull a couple plugs IMMEDIATELY following a spray. Chances are they are real white. I would suggest going with a smaller shot until you figure it out.
Flashing SES is random missfires. The computer does NOT throw a code if you are lean at WOT in "open" loop mode. How many times has this happened. Have you pulled all of the plugs? Usually when that happened to me I had popped a couple plugs. Another "clue" is the converter wont lockup if the missfires continue due to a popped plug. Consider yourself lucky if theres nothing wrong, I HIGHLY recomend not spraying the car again without a wideband, Perferably on a dyno with a tuner present. This could be a timing issue if your still running stock timing with a 150 shot

it happens everytime i spray. and thats like 2 or 3 bottles ago. the last time i changed plugs and they were pretty white but i just figured that happens when you use nitrous.
White plugs = lean = not good. 
Don't spray anymore until you find out your a/f through a wideband and/or tuning unless you got money for another motor. Flashing SES light isn't good neither. Start checking ignition related items first: Plugs, wires, coil, etc. Just hope you didn't pop your motor.

There seems to be some confusion among the posters in this thread about how to read a spark plug so I will provide a link with the proper method of checking plugs.
