Help! Built LS1 won't idle! P0102 Freshly built LS1 will not idle on its own, has the following mods:
Fast 102 intake/TB
PRC 227 Heads
Ms3 Cam
SLP lid
42 LB injectors
Longtubes
True duals
Car starts up and runs great, drives great, however at idle it just dies unless you feather the throttle. The only code it's showing is P0102. The car is of course tuned for the mods have had several re tunes with no luck. Open to any suggestions that may help solve this!

Post the tune. That cam will take a little finesse to idle. Sounds like you don't have the TB cracked open enough to feed it air at idle. And, as 2xLS1 said, you're probably in Open Loop for no fuel trims and in SD mode (disabled incorrectly) for the P0102 code.
