12a turbo motor will not idle ......help please.......
Hello all
I have a 12a turbo motor running stock boost and turbo and manifold that was running fine the other week and all of a sudden it won't idle.
So i looked around and i seen a rubber block of hose on manifold that was missing and i replaced that with all new block of hoses.
And problem still is there will not idle just stalls tried new plugs and everything.
I did touch a screw on the throttle linkage to try and turn idle up but it did not both ways.
it use to idle at 1400rpm and now it just starts up and it stalls if i hold it at 1500rpm very still it's fine it will idle nice and rev nice to.
If i take it out the road it rev fine drives fine and everything.
It's like it has a air leak but i can not find it anywhere.
I can not turn idle up either can not fine the screw anywhere to adjust that.
Can someone please help me out so i can fix this problem
The car was fine before the old block of cap fell of from age.
there's a couple screws where the throttle cable is can someone tell me what there for please.
This picture has got couple arrows can anyone tell me what these screws do on the throttle arm.
What do they adjust anything or nothing
aALL YA HELP WOULD BE GREAT

Problem fixed now it was 2 small vac hoses that i coulden see was giveing me a lot of trouble.
They were split from age ya woulden belive how a vac leak could cause a motor to run like ****.
If anyone else has symtoms like this check all ya vac hoses and vac block of hoses.
The throttle screw with arms of them they adjust tps sensor so don't touch them.
