my car is not running right

i was driving it around and it went lean and died

so i had it towed back to my place

i changed the plugs and had to add 50% fuel correction in safc 2 to got it to start

if you try subtracking fuel it goes lean and dies

it idles at 13.0-14.5 but if you give it gas it goes lean and dies

the only way to rev the engine is to slowly give it gas

but if its in gear any amont of giving it gas it will go lean and stall

it has 550cc injectors with ls400 maf

so whats causing it to not get any fuel?

help please

Is your maf hooked up/working/on the right way? Could your fuel filter or pump be clogged or bad?

jth3rd

i try swaping out the maf made no differnce.

jth3rd

okay i have fuel pressure at the fuel rail i removed the fuel return line and got sprayed with fuel

so could it be the fuel injectors, or a sensor

whats your fuel pressure at? are you using an afpr? it would be nice to know if your getting the correct pressure at the rail.

edit: how many miles have you put on it na-t since this happened? is this your first time out with it?

jth3rd

since first start up, but it got worse after the taking 30 min drive it then it stalled had to tow it back.

i change the plugs with ngk and gaped them at 28

and it still will only idle. give it gas leans out and stalls,

with 50%+ cor

tps is good, idle speed sensor is good, maf is good

i pulled the plugs and there showing lean

i went to autozone then oreillys and napa none of them rent out fpt

so i still dont know what my fp is at rail

Air, spark or fuel, i would do a leak down and compression test to see if any thing is damaged internally.

when you removed the plugs, did any of them look abnormal I.E. wet, oily, carbon coated, etc?

jth3rd
