Car is running great now. Dyno'd at 209HP/209TQ @ 5PSI on a DynoJet. Read last page for details.

 

even though you checked all the the vaccum lines it still sounds like a vaccum leak. Did you check the injectors? The rubber seal on each one? One may not be seated correctly. Next check all your couplings for anything loose. Next thing i could think of is to check your intercooler for anything damage, i.e., dings, pin holes. Vaccum could make the car run like crap and also air getting into the plumbing after the maf could cause it to idle poorly.

 

couldn't this also happen if he's running lean?

 

I just went back outside and fired her up and its running real lean. Like 17AFR lean at idle. Must be the injectors or an injector. Could it be anything else? Thanks prototype xB. I'll check those again as well.

 

I'm gonna go with running lean - engine is starved for fuel, therefor it keeps stalling.

 

man jarod, what happened? you just got this kit and theres problems already!!! haha....just playin'...you had it tuned right? what was the boost gauge reading at idle, sepcifically in vacuum....i know mine hovers between 20-22 in vacuum.....if your afr reads 17, then you definetly have a fuel problem.....

 

Yea the crazy thing is, I have an appointment on saturday to get my car tuned! I've been driving it fairly careful, apparently not careful enough! I'm even running larger, 440cc, injectors. I'm wondering if one of the injectors just called it quits. When I take them out, is their away to see which one is bad? Should I get an OBD-II reader? I'm already throwing a CEL because of no cat. ____e! THanks for your input guys.

 

might be a bad o-ring on one of your injectors.

 

thats what she said...okay i'll leave i don't have any knowledge that can contribute to this thread...

 

it mite be werd.. but check ur pcv valve.... also.. it mite have popped off.. it that will cause a rough to stall idle..

 

But would that cause the car to run lean? I'm talking off the charts lean. My AFR gauge won't even read how hi. I have the AEM UEGO gauge. My installer is supposed to come by tomorrow, I guess I might have to put my stock injectors back in just to get her up and running.

 

you gonna need a ride to work in the morning or what!? could be numerous things, let me know what your boy says.

 

i had the same thing happen and i took the engine cover offf and the vaccum all the way in the back came off it was very hard to find but it was the vaccum all the way in back of the engine cover came undone i just took some zip ties and called it a day, idle went right back to normal, does ur bov sound funny when u let off the gas like it makes the gobble sound instead of the loud whistle it should?? and what kit is this were dealing with?

 

he has a treadstone kit.

 

God I hope thats all it is! It was dark when I was looking around so maybe I missed that vaccum line. I just have a feeling its a fuel injector, since its running lean. A vaccum line coming undone doesn't cause lean conditions, does it? I'll keep you guys updated.

 

LOL, I might be hitting you up for one man! I'm so irritated since I have an appointment to get my car tuned on Saturday! God I NEEEEED it to just be a vaccum line. Wanna buy a turbo kit chirs? J/K

 

what kinda injectors come with there kit?
have you talked to treadstone about ur issue?

 

Old trick is to spray some starter fluid around areas that have intake hoses and junctions - when the idle smooths out from the starter fluid being sucked into the engine you found your vacuum leak.

 

It comes with 440cc bosch injectors and he hasnt talked to treadstone yet. The guy who installed his kit is supposed to come over after later today after he gets off work. Its runing WAAAAAAAAAAAAY too lean to even drive it.

 

LOL, what mighty said.
