Your opinions are about Oooooo 7-8 months too late but nice try... now *facepalm* yourself

Page 3... I know its a long way into this thread, but you made it to page 11 so Id think you read it all :th_laugh-lol2:

Is this what you were considering at first??? I came across it in another thread and it made me think of you, for the I5 Colorado/Canyon/H3 Hummers. I know its alot more than your turbo setup, just found it and thought Id mention it.

BTW.... get her tuned yet???
 
yeah there's pics of that s/c on page 3 or so i think.. i considered it but they want like 4 g's for it, no one know what kind of numbers it puts down, and there's some custom fab work that needs to be done for the throttle body/intake or some**** to make it work because it's actually made for a hummer 3

i haven't gotten it tuned yet because the new engine is not running right for some reason, i need to do a cylinder leak down test and test the fuel pressure, then go from there

Ya I noticed the pics and figured that was what you were looking at.

:th_nervous: Dont Say That!!! Gonna make us cry. we need positive results, not more bad :(
 


yeah, i've about f*cking had it, i can not for the life of me figure out what is wrong.. i fire it up and it runs like absolute sh*t until it warms up, i've swapped, O2 sensors, MAF, MAP, coolant temp sensor, exhaust cam actuator, pretty much any sensor u can think of, and it still does it, and i've checked and rechecked for vacuum leaks
 
If it runs fine warm, if it is a valvetrain issue or an oiling issue you could run some thin oil through it to wash out anything that might have been sludged up from sitting
 
i dunno, i'm gonna borrow a leakdown tester and see whats up.. but i would think a valvetrain issue would at least cause misfires no? when i fire it up it runs really lean like in the 17/18's
 


that was my thought also.. a bad coolant temp sensor would cause issues until the PCM switches into closed loop (when the engine is warm).. but that's not the case... i've already swapped every other sensor i could think of..
 
is the BOV operational? if it's stuck closed, your MAF could be getting a wrong reading and causing the pcm to send too much fuel. i'm kinda reaching here though. it might just be in the tune
 


so i did a leakdown test today and it show each cylinder at 10% or less leakage... so it seems the valves and rings are in good shape still

have you checked for injector consistencies? take a multimeter to the fuel injectors to see if they're getting the same signals
