hey honda tech... i need help i have a h2b,
h23a blue top vtech
b16 lsd tranny
skunk 2 intake manifold
plm 4-1 headers stock throttle body.
after i put the swap together the car has been idling up n down idk what could be the problem.. when the i bought the skunk 2 intake mani the icv was block off. idk if that could be the problem or the tps sensor.
my boy with a h2b said its a vacume leak. could that be? thank you

 

what kind of ecu are u running, did you run or block off the coolant/heater lines to the TB, and IAC?

 

based on the symptoms you listed I had a similar issue with my b16. I had the wrong TPS sensor on. Also I had to flip my TB gasket so the map could get more air. Problem solved.

 

It's my old ecu from my b16 but a basemap for my h22 idk where the hoses for the iacv goes.. I bought a new one bc I didn't have one it was just blocked off..
