Couple quick questions.
Couple quick questions. Okay, I just got my intake manifold back on. I had it powdercoated and the tb side bored for my 58mm tb. I also deleted the air and egr. I also put on long tubes. I have a tune with the air/egr deleted and setup for what I have done.
Now, The car idles higher than I would like, around 1100 rpms. I am presumming a vacum leak, but cant put my hands on it. Any suggestions where to look? Where does the line on the top passenger side (above the one that goes to the fuel pressure reg) go to?

Yep got block off plates on the back sealed with black rtv and a good gasket between the tb and the mani, torqed to 18ft lbs.
I do have a small leak around the elbow, but that should not hurt idle should it?
So spray starter fluid around the seal of the tb and the mani and it will cause the car to stumble?

Check all the ports on both sides of the intake and see if they are connected or capped off (brake booster vacuum line, PCV hose, fpr hose, hvac hose, egr solenoid hose, opti vent hose, hose from TB to pass side valve cover, hose from TB to EVAP, etc.) Spray starter fluid like mentioned, at every sealing point of the intake, the seal of the TB, the ports, the intake elbow, anywhere you can think of.
That is probably my problem, because I know I have a leak where the elbow meets the tb, as it is split in a couple places. I didn't think about a diff amount of air into the motor vs what the maf sensor is seeing.
