i have a 92 prelude and i swapped in a 96 h22a1, i converted everything over to OBD1, i have a p13 ecu for it. im about to put it on the road but im having a problem with my car stalling out. im trying to findout what is wrong with the engine so i go to check the engine codes and the end light says on. which usually means that there is an ecu malfunction. which cant be i just bought a new one and the car idles great but when it hits 4,000 rpms it dies? does anyone have any idea???????

 

sounds to me like you switched your MAP sensor around with your TPS sensor...just did an LS VTEC build, car idles great, stalled out at 3500....give it a shot, just double check all your wiring
