I have a 1990 b18a1 swapped into my crx that was already done when I bought it. It is all stock. Anyways today it started having major power loss like it did before I fixed the o2 sensor harness a month ago. It is hard to start, shuts off when i'm coming to a stop. There are vacuum hoses not connected and my purge solenoid is missing. Is it suppossed to be like that? Is it possible that it doesnt have a map sensor too. Anyway, i'm wondering how to fix all this if it is even worth fixing. I have dumped so much money into this just havent done the engine problems till now, so I dont really want to give up. Please help I need to be able to get this car running smoothly so I can drive it to work.
