Hi. I swaped in a 98 b18b engine into my 94 integra over the weekend and I still can't get it to run right. If anyone can help that'll be great. Problem -As soon as I step on the gas and let go the rpm drops really low, almost killing the car. -When I shift, or attemp to drive the car it seems weak and bogs. My rpm idles around 1k and when it bogs, drops to around .25 or so. I used my old obd I engine harness and swaped over the dist. and injectors. The 98 engine didn't come with a throttle body so I hade to reuse my old one. -The only thing I didn't connect and decided to plug up is the thingy on the bottom of the throttle and one of the coolent hose on the side of the head, because I couldn't figure out where it was suppose to be. The place where it's suppose to be isn't there on the obd II engine. Any help or suggestion is greatly appreciated.
