Just installed a b20vtec and it will not idle. It also back fires when it stalls. I checked spark plug and their wet. I'm using a chipped p28 with a base map for a gsr. The injectors and fuel pump are aftermarket upgrades but I don't have the specs for them. They were purchased five years ago for my b18. I have a wideband o2 sensor and I plan to set my ecu up for datalogging soon, just waiting on my datalogging cable. I'm using crome to tune. Anything I can do to get the motor to idle?

some info of the set up:

b20z block
JE pistons (cr 12.1)
GSR head
Skunk 2 cams

lmk if more info is needed.

thanks
