i recently swapped a JDM B16A in my hatch. Everything went well started up fine threw no codes runs good until i go full throttle. It will go and after about 3 seconds of full throttle it will cut out and kick back in and cut out again. I changed my fuel pump but still no luck! car will pop vtec and run fine all the way to 8000 if im like 3/4 throttle. Anyone know what this could be?

 

Are you saying it's crossing over into vtec and then coming back out over and over again at full throttle?


Do you have a mechanical oil pressure gauge? What ECU are you running?
