fresh rebuild wont stay on!!!
im having an issue with my new rebuild, itwill not idle at all....it whistles in between revs now that i swapped the TB and UIM, i had a throttle body before that didnt whistle but it didnt seem to get the car going at all!!! i have got the car to stay alive but its still rough even when trying to keep it alive....rpm jump to 3k rpms right away i cannot keep them in between unless by coincidence...
YES i have searched and found this thread but i wasnt too sure i wanted to revive such an old thread:
https://www.rx7club.com/showthread.p...+manifold+idle
its a GXL, streetported 13bt using NA s4 rotors, using the NA wiring harness and all T2 electronic components: ecu, maf, pressure sensor, intercooler, s4 ported turbo....
it has 660 secondaries and a walbro 255 fuelpump...
i will post a video up soon... thanks.

check in between the TB and your "elbow"(you know that rubber triangular seal,in between the elbow and the TB?)..it sounds like a Vac leak for sure.
I'd be checking all vacuum areas.just to be sure.

your manifold isnt sitting right. at least that is what has been the cause for me when i hear that whistle. ever since then ive always just put a small bead of ultra black rtv on every joint

ill check, but i think the Mani is just hanging over i have the intercooler bracket but maybe it is causing stress on the LIM to UIM gasket... i didnt use rtv i just threw in the gaskets because i didnt want to keep having to remove the manifolds and mess up new gaskets every time i removed the manifold.... i will look into it for now, i kinda figured that it wouldn't make a leak if i didn't add sealant....

misterstyx69, it was the elbow that u had said. i took the UIM/the tb and the wlbow on the tb off and pressurized it with a pipe and sure enough it as leaking through the elbow, making the whistle....
but that JUST fixed the whistle not the car has a hard time staying on....starts up fine and stays on for a a minute or so, and just cuts off, could it be the thermowax pellet? or what could it be?

my turbo is leaking coolant and smoking lightly, but i know for a fact that its not the turbo... could it be? the turbo it seems fine it will be replaced soon, but its a constant leak it the leak i believe is coming from when i ported the turbo and put it back together its leaking on the hot side by the coolant feed... again the car ill stay on but i have to keep it alive.....

OKAY, now the car stays on but only stays on and idles nicely when started COLD, it will stay on untill i give it gas, then it dies. after it dies, it doesnt want to start again, unless i keep it alive.
like f a vacuum leak is created when the car gets warm/hot..
could it be the thermowax??? becuase it idles nicely then when i give it a light rev or a heavy rev itll die....TPS is at .99 to 1.01 it varies. all vacumms have nipples or they have a line on them...i need help guys... this is frustating its been almost a month since ive gotten the engine back from the shop.....
thanks.

You said it was a fresh rebuild correct? Well you are going to have a hard time keeping it below 1K untill it has got a few hours of run time on it, get it where it is idling around 1200-1500 and let is idle for a hour or so, checking for leaks and watching the coolant temp.
It should start running better after time, but another video would be nice.
