I'm posting this for a friend. We just got done installing a new jdm h22 into his eg (already had swap, it blew up) and are having issues with power cutting out. he's running hondata s300 with a innovative lm1 wideband, dc header, tanabe exhaust. Last night it was bogging and falling on its face throw low to mid rpm/throttle but when he floored it, it picked up and slammed vtec and hauled ***. this morning its the complete opposite and bogs with more throttle/rpms. The air/fuel looks right so we're having a hard time figureing this out. I tried searching and found nothing. Any ideas?

 

check the iacv maybe when i had the 3 wire one it bogged at WOT. Then i changed to the 2 wire and it worked fine
