I have went through my whole fuel system and cleaned, blew out, or exchanged 805 of it, new walbro 255, 4th fuel filter,(now staying clean) 2 fuel regulators, relay, and cleaned rail... Problem is, I found 2 injectors not working, I blew air back though them( as suggested by someone) and 2 would not work, So I need them, Everywhere Ive called has been no luck, I have the car traded for a vette if I fix this, the car only has 65000 miles its a 94 lt1, I replaced broken tranny when i bought it, it had sat for 3 yr. I may keep it if it runs as Ive been told after the fix... as of now it runs the same as my 96 gt mustang lol... so it needs help
