Lost power during nitrous pass
Hi All,
Was doing nitrous passes the other day and all of a sudden the car started to lose power. I let off the gas and the rpm's got lower and lower, until I cut the car off. Let the car sit for a bit and tried to restart. Car will turn over but will not start. Threw two odes p0300 random misfire, and p0101 mass or volume air flow circuit range/performance problem. I also smelled slight burning for just a second. I am thinking it has to be MAF or a burned up plug. Has to be air, spark or fuel related. Any of the nitrous guys out there ever run into anything like this? Want to eliminate the small things first. Hoping there isn't a larger issue.

How many miles do you have on the plugs? Curious if you run colder plugs when running nitrous?

So took the car to my mechanic and they said it was a nitrous backfire. Blew off two vacuum hoses and need to replace plugs. Leak down and compression tests show no issues with the bottom half, but they think a valve got stuck open. Either a broken rocker, valve stem, or something. Will know more this week.

Did you happen to run out of Nitrous or run the bottle very low? Check your bottle and see how full it is because if it wasn't getting enough nitrous with your extra fuel being dumped in, that could be your problem. When I had a misfire and had the same code you did, I realized that I was driving around with my system engaged but my bottles were closed. Every time I hit WOT, it was dumping more fuel into my intake but no Nitrous which caused a misfire in cylinder 8. This also lead to a loss of power and a shut down just like you had with the check engine light and the same code. I make sure to check my nitrous engage switch every time I enter the car now, I have It set where my knee can hit the switch... oh well. Its on a progressive controller so it only engages on WOT.

Nitrous is relatively safe on the F.
