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.

upload a log or can t help

did you rescale maf after installing CAI? but yes i would also think of a leak, check also the hoses under manifold

+1 for logs.
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 ��
