Crawford Power Blocks idle issue
First post on this forum, I got the Power Blocks with the Grimmspeed CAI and Openflash tuner. I started my car and it would rev up and down through 1k and 2k rpm, bogging down when it gets below 1k rpm, and shuts off after around a minute. Im on the Stage 1 tune and I flashed it when I put the CAI on. All the PCV hoses are attached and everything is plugged in correctly from what I could see.

Id recheck everything. it sounds like your idler control isnt functioning right so you got a leak someplace.
otherwise try adjusting the tune for the power block spacers. https://www.ft86club.com/forums/showthread.php?t=71285 |

Based on that it would be a lot easier. But my guess you pinched a gasket or it dropped/fell out and you got a bad vacuum leak. |

UPDATE: Found the problem, the gasket on the driver side of the manifold slipped when i put the blocks in, and when I tightened the bolts down, it must've cut the gasket. Ive already ordered new gaskets. Thanks for help ��
