long story short I bought a toyota cressida with a 1jzgte that has -Top mount single .70 t3 turbo, apexi neo safc 2JZ timing belt / water pump / cam seals, USDM 2Jzgte fuel injectors,
Aeromotive fuel pressure regulator, Warlboro fuel pump. As of recently she went from idling around 750 rpm down to around 400 rpm barely alive, once I get the gas to rev it up a little bit and let go of the gas she stalls out along with that I've been looking for vaccum leak areas due to the fast I was reading about -10 vaccum at idle. Now she is at a flat 0 and oil pressure has dropped as well to around 12 psi. I'm curious if their is anywhere I should start looking to regain my idle, oil pressure and vaccum.

Check for vac leaks, bad coils and the infamous bad capacitors in the ECU.
