Hey, i just installed the delbrock turbo kit and i'm getting an idle surge from 1000 to 3000 and back to 1000 non stop surging, now is it possible that a intake manifol vacuum leak can cause this surging because i overchecked all my wire connections, my tps sensor, the iacv, the map sensor and everything seem to be fine, i remember sensing some air commin from the intake manifold but i didnt really pay attention to it....could a leak be causing this ??

yes it can.

also air in the coolant if you didn't bleed it out can cause a surge. and also make sure you didn't get any of the sensor plugs mixed

I had similar symptoms when my hose for the PCV had a hole in it.

well, if i disconnected some hoses to change a couple of things around i guess there was air that got in the hoses, is it possible ??

if you took any water lines off the engine you would need to bleed it out

how exactly do you bleed it if you dont have a bleed screw ??

Is it possible that you have to pinch the top radiator hose to get the bubbles out ??

I'm not sure. maybe you can start engine with cap off an fill as needed. bump, maybe someone else knows
