the only other thing that makes sense to me is if for some reason the computer is not pulsing that injector the same as the rest cause it's multi port??

not very likely that only 1 injector would be affected by some kind of injector timing problem, unless the injector itself is bad.

I would get a pump just for the hell of it. Mine went bad and it was causing stuttering and stalling problems.

how bout the possibility that the distribution to all cylinders isn't on 100%?

I ran a 150 shot on my car for years with the stock fuel pump. Maybe there is build up in that injector? What type of nozzel are you using and where is it plumbed in at?

I'm using the one that comes with the Zex kit (mixes fuel/nitrous at the end of the nozzle). I have it mounted about 8-10" before the throttle body. I thought of the possibility of all the juice somehow shooting to that one cylinder, but I would think that, especially with the trick flow intake, there wouldn't be a problem with that.

All the juice in one cylinder would make it run pretty shaky, way off balance just like if it was misfiring.

what u need is a jacobs ignition

that is the stupidest thing I have ever heard.


Although some people do manage to run big shots of nitrous on stock pumps, you can never assume that one pump is in the exact same condition as the other. Start by upgrading your pump, and if you are still having an issue, you should look into buying a set of SN-95 fuel rails. It was a common problem on the 351w trucks that the #5 cylinder (last one, furthest away from the feed of fuel) would run lean and almost always kill the engine. The reason for this was excessive debris build up in the end of the rail, causing an obstruction in the fuel flow path.


take it for what its worth, but ignition isnt your issue... fuel is!

The rails on my stang though cross at the front of the motor. The crossover meets right after the #5 injector, so technically the #8 injector is the furthest away, unless there isn't enough pressure to run back up the rail to the #5.....
