car wont idle after putting back to stock

[loreak]

i took everything off my car and put it back to stock and it wont idle, it now has stock injectors and fpr, mas, turbo, ecu, so it should just start up and idle fine

if i start it i can rev it up and hold it at like 3k and it sounds great, if i keep the gas perfectly still it does kinda blip, like revs drop a few hundred rpm then rise and it seems to slowly step down in rpm without me changing the throttle at all

i had a nasty leak at my intake manifold gasket but its fixed now so i dont think its a vacuum leak, it just falls and dies under 1300-1500, doesnt surge at all, just goes strait to zero and dies, it hesitates just the smallest bit before it dies

Did you reset the ecu when you did this all?

It sounds like a vaccum leak to me if it wants keep dieing.

well the battery was disconnected for about 2 months so id say the ecu is reset

i gotta hook up my leak tester when it gets above like 15 degrees haha, i want to work on it but its so damn cold now

ill tell u what, its a pain in the ass messing with it when its this cold, the wire loom around the injector plugs and alot of the harnesses is like rock hard, its like bending a piece of iron trying to move them out of the way

Yeah it was 3 degrees here in upstate NY. :thumbdown

1. Check and make sure the mas is pluged in and no leaks at the intake pipe couplers.

2. Do a boost leak test since you've install a different turbo.

3. If all else fails, put everything back again and reinstall the stock parts one at a time to narrow down the problem.

mas is fine, im getting a good aircount on my afc and its sealed good

i dont have any of my stuff, i took off a TON of stuff and sold it all so whats on now is what i got, i hooked up my leak tester but i had such a bad leak in my intake manifold gasket that i couldnt tell if i had leaks anywhere else, its been too cold to test further

my intake manifold gasket had blown out at #1 cylinder like the entire bottom of the port, i had 30psi going into my leak tester and my boost gauge showed 2psi , but thats fixed now
