I just finished dropping a b17 with a hydro ls tranny into a 93 del sol. the computer is a chipped p28, no knock sensor needed, only minor modification to wiring was needed because the car was an si with a sohc vtec. all vacuum lines and sensors are hooked up correctly as far as i can tell (though the MAP sensor is dangling by a vacuum tube) save for ONE unnamed connector of a green color in the back near the knock sensor. my manual makes no mention of it and i don't, as far as i know, have the right connector for it though several will fit. anyway, i start the car after the swap, it sputters, runs up to 3500 rpms and idles here. when i apply pedal, the motor coughs and rpms drop, and at wot pedal position the motor dies. it does this upon repetition, so i scratch my head, check all the tubes and connections, make sure the throttle cable is ok... anyway no change. i reset the ecu by pulling out the fuse, try it again... the engine runs up to 5000 rpms ( at idle throttle) before i get nervous and kill it. it does this every single time up to the last time i've tried it, and any pedal at all will nearly kill the engine. the strangest thing about it all is that the engine doesn't throw a code, and aside from trying to leap out of the engine bay and run down the street, it purrs like a kitty. so where am I at? any ideas? thanks...
