    Hey guys this is my set-up 95 civic ex with a jdm b16 obd-1 with a Gsr tranny and usdm P72 ecu.
    I just completed my swap a few weeks ago and the car runs great Vtec kicks assss.... i'm just having a problem just before the car hits Vtec . Around 5k-55k the car goes on limp mode for a few seconds and then it rips to red line ... I understand that ecu is throwing code 21 Vtec pressure switch " I heard that Jdm motors dont have this particular sensor"??? ALso IACV CEL is on as well >>?? Will this cause my idle to be surge from 1k-2k while the car is warming up... After it warms up it stops surging and idles at 1k. I think i have a vacumm leak cause i hear a hummin sound when the car is at idle ... Please guys if u have any suggestions let it out !!!!!
