My 04 turbo colorado (build, destroy and rebuild thread)

do what? they are black lol

[TLSheff]

very nice maybe get some black rims 4 it? my opinion

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

[Supercharged99]

What would really be cool is if you got a black speed grill with some sort of red "chevy" script....oh wait....

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???

[BLKGP]

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.

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

[BLKGP]

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

[Fivefingerdeathpunch]

fuel pressure issue??

[Kejross]

Lifters or valves sticking from motor sitting in the junkyard for a long time maybe?

[OH4CompG]

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

[BLKGP]

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

[Poil336]

re-re-re check for vacuum leaks? that does seem electrical though

[BLKGP]

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..

[Poil336]

maybe a simple question, but is this a stock pcm youre running or one that you tried to tune on?

[BLKGP]

it's stock tuned for the 60# injectors at the moment.. no turbo tuning yet

[Poil336]

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

[BLKGP]

i don't have the charge pipe hooked up, so the engine is running N/A at the moment

[Poil336]

well sh!t

[BLKGP]

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

[Poil336]

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