Stuck injector...how to fix???

[Florida240sx]

Found my vaccum leak. Hose was disconected under the itake mani. My #3 injector is stuck open.Anything I can try to do to fix it??? I replaced o rings thinkign it was that. My #1,2,&4 pistons have black on top of them. While my #3 piston and spark plug has gas over it. All the plugs are fouled out from the vaccum leak....

So any tips on trying to free up the injector???

Won't hold idle. Spit and sputters. Seems like I got a vaccum leak again. I was pulling out my driveway for a test and it started messing up bad. So put it back in reverse and was backing up, an dit stop sputtering and hit boost, Almsot smacked my head on the steering wheel.

It doesn't idle. It trys to idle at 500-700 and a/f ratio is at low 10's fuel pressure is at 30..When I fixed the one vaccum it went down to -20 slowly and started sputtering again, since then I can't get it to go back below 10...

that sucks man sorry to hear youve got some problems still. youre better than i am because my car wont even fire up now. i just went out to make sure i have fuel and i do. couldnt check spark by myself, so im not sure if i have that or not. i moved the maf back to the cold pipe to where it was before when it ran and it still doesnt run. i meant to check the plugs and clean them, but i forgot and remembered while i was in the shower so too late for that. im really getting bummed out now. im at the point to where i dont give a fuk because its been so long since ive driven my car.

Think I got aother vaccum leak. I went in put in 6gallons of fresh 93 octane and car ran a bit better.... The gas did smell stale which is about 4 gallons of it....My car is spitting and sputtering, but If I can get it above 2500rpms it will drive and at 3500rpms it want to go. But just spent 3months and 2k to ge tthis engine and don't want to mess it up....Does it turnover? Tell me what you got. 386-747-9982

yeah my gas is pretty old too. it was really dark when i had it spittin into a dr pepper bottle to check fuel. id say my gas is about 3.5 months old at the most. i know what you mean about spending money. i spent over 4k on my entire build and kat setup and look where im at. yeah im one bummed mofo. and yes it turns over.
