I finished up my m62 install this afternoon and was trying to top off my coolant by starting the car to circulate the coolant, but the car won't stay running at idle. If I hold the accelerator to about 1500 rpms it will stay running, but one off the gas it dies. The car has not got to the dealer yet to get reflashed (going on monday), but is that normal? Is this the computer not being able to read the new TMAP sensor or a leak somewhere in the system?

Straight from the performance book

54. Use the 90 degree elbow from the original vacuum line
and install it on the can. (Fig. 37) and (Fig. 38)

Is that all you do or do you T it in with the FPR into the port on top of the intake mani?

Umm... lol. That is expected to happen... you can't just change the MAP sensor and fuel injectors and induction method to something more an expect it to run properly.

I actually figured it out on Saturday. It was a bone head move on my part. I forgot I had to machine out the part for the IAC on the TB adapter I made. Put it back together after machining it, and it idled without having to hold the accelerator.
