I have a 95 eg with a 2nd gen b16 motor. My Idle is way high(3000 to 4000rpm . I replaced my map sensor and my tps sensor and even made sure that the idle adjustment screw was as low as it will go. I even made sure that the timing was correct. The map sensor does not go on the throttle body like I have seen on others. What confuses me the most is that when I unplug the map sensor hose the idle drops down where it needs to be, but then it runs rich and black smoke comes out of the exaust, and the check engine lite comes on. I was wondering if I have any hoses going to the wrong spots. Could anyone help me? If you could send pictures of how yours is and where hoses are going, it would help. Thank you.



p. s. The last time a machanic looked at it he pinched off the hose coming out of the bottom of the sensor on the back right of the manifold.

 

First, what have you done to your ride? like any mods??? To me, it sounds like vauum leak. Yea, check all your vacuum hoses for vacuum leak and importantly, check your Fuel Injectors to see if the O rings are losen or worned out. If they are, then you need to replace them or tighten them up if they're loose. Cause those injectors's seals are VERY VERY important, it can cause for gas leaking and Will make your car detonate as well as your RPM goes up and down or missed adjustment. Just for your security, Do Not Drive your car for 10 mins after messing with the Fuel System (ex: fuel pump, fuel injectors, any fuel source) Let it idle for about 10 mins. Hope this will hellp!

 

I figured it out today and fixed it. It was the cold idle valve. nice
