D15B7 Engine help
Ok well i recently got a 1993 Honda Civic DX and I noticed that it idles really high. I got a cluster with a tach and see that it idles at just about under 2000 rpms. So I think it has something to do with a vacuum leak because there are some hoses that arent connected to anything on the engine. Only problem is that I dont know where they go. I have a picture below that circles the hoses that arent being used and the one just has a bolt in the end of it. So im just wondering if anyone knew where these run too.

the metal ones are coolant hoses, why they are not hooked up i dont know, try starting your car, and then adjusting the idle screw on the throttle body, it takes a flat screw driver, turn one way or the other till it idles where you want it, about 700
the rubber one looks like your pcv valve that prolly needs to be hooked up it goes under the intake to a block box on the back of your block

Yeah, especially considering it goes directly to the map sensor. The sensor in the pic is a throttlebody mounted MAP sensor, found on the '94 - '95 D15B7s, '92 - '93 D15B7s used a MAP sensor mounted on the firewall next to the fuel filter.
