5vz-fe Will not idle
Hello, I just finished a month long head gasket change on a 96 t-100 with the 3.4l 5vz-fe v6 auto tranny. It now will not find idle. In order to get it to start I have to feather the accelerator peddle. But once I turn on the A/c or hold it at about 1000 RPM it will find idle and hold/correct it in and out of gear and with and without the A/C on. I think I have all the vacuum lines on correctly but its been 4 weeks since I last saw the engine assembled. Any ideas or vac line diagrams? The FSM shows them but not in great detail.
P.S. The truck also has no EGR...

I do have a scanner and will check for the coolant temp sensor to show correct readings. No check engine light, maybe hidden codes. Spent 2hrs flushing very rusty coolant. It slowly started working better but is far from correct. I notice if I push the a/c on button it immediately starts working and I can let off the throttle.
EDIT: Thanks for the speedy late night replys
