So as the title says my integra randomly cuts out at the higher rpm range. I recently did an h22 swap into it so I posted this in the hybrid and prelude forum but no one's helping me so I'm hoping theres some smart people here in the integra forum. So anyways, when I'm driving, itl cut out anywhere from 6300-7000 and just abruptly cut out, feels like a rev limiter, and the engine recovers from it fine. I'm getting no cel's. O and also I can rev to redline if I give it half throttle but every time I give it WOT everytime it cut's out. Please somone help me, it's bugging the crap outa me. Thanks for any help in advance!

 

check your thermostat ground.

 

ECU???

 

How would i check the ecu to make sure that's not the problem. And I'm pretty sure my thermostat ground is on pretty good. Any other idea? please help this problem is driving me nuts.
