man i dont think this is right update first post
 

so my car is fucked up. whats new.
my question is could the fact that my downpipe cracked before the o2 sensor be causing it to run pig rich and die at idle?
the vacuum flutters around 10in/hg like a faggots eyelashes and it smells like an old boats exhaust. but the car isnt throwing any codes.
it will idle at 1000 sometimes but the minute i go anywhere and let off the gas it drops to 500 and wants to die.
man i am in way over my head on this ----.

update,
checked for vacuum leaks. none.
reset ecu. nothing.

getting alot of blowby, i think that my valves are broken in, need a lash adjustment.

iacv blocked off, car wont run when cold. very bad idle till warmed up completely. then idles fine.

Re: car wont even run to run like shit
 

what was the last thing you changed, like any new mod, replaced part, anything? problems like that dont just happen. and no, i cant imagine a cracked downpipe causing much of any problem but noise

Re: car wont even run to run like shit
 

need all the info on the setup

Re: car wont even run to run like shit
 

check cam timing

Re: car wont even run to run like shit
 

i havent really changed anything, just put a new turbo on. but that went fine.

setup
d16a6
vitaras
272 cam
t3 60 trim
b18 TB
ported intake
xeno basemap
yada yada yada

ps just found that a line off of one of those things by the map is off. not the line coming in but the line going out. not sure what it is or where it goes but i will look into it tomorrow.

its the two solenoid things by the map on the firewall
the one on the passenger side, top line is off
anyone know where its supposed to go?

Sounds like a dizzy problem. :-\

Re: car wont even run to run like shit
 

no sounds like a vacuum leak.

check int. wastegate, vacuum tee's etc..

yeah im going to put the smoke machine on it when i get over to my uncles shop.

Re: man i dont think this is right
 

so i put new plugs in because the others were fouled, i thought the car is running way to rich and is fouling plugs because its just a base map.

well i finally got my jaw up and running and and getting and afr range of like 12.5 to 16/17. which i think is too lean??? maybe or am i ass backwards and thats too rich?

im not sure but i know that it is really off, could the crack in the downpipe be making it read wrong?

Re: man i dont think this is right
 

yes, because its before your sensor. i gotta say "duh" on that
