Need help! I've spent hours searching for threads that were identical to my problem but had no luck. I swapped a jdm b20b into my 98 ek hatch. Everything is wired correctly (triple checked) but the car won't start., and when it does it goes straight to about 4000-5000 rpm and and then shuts off. CKF bypass done correctly as well as the 3 wire to 2 wire iacv. The motor cranks fine but when it does start up, it's as if the throttle is wide open. I swapped the plugs for the tps and map sensor just in case I accidentally mixed them up, but no luck.

My set up is a 99 jdm b20b with a skunk 2 intake manifold, skunk 2 70mm throttle body, aem fuel rail with fuel pressure regulator, obd2 LS injectors, obd2 LS distributor and a obd2 P75 ecu.
