My car setup is 1992 Honda Civic VX w/ 1995 GSR swap.
I seem to have a similar problem, but is more extensive and will need experienced tech help. Thanks to all who help out.
The problem is 3 consistent problems. They happen every time I drive my car, and it happens the whole time im driving my car.
- The first problem is the idle. It idles really high. 1500rpm's. And it idles roughly between 1500-1200rpms. But, whenever I pull back on the gas pedal, it sets itself back down to 1000rpm's and stays there. As soon as I start to press the gas again, it idles again a t 1500-1200 back and forth. I put a brand new GSR throttle cable on the car as well.
- The second problem is my speed stability. For example, I cannot cruise at 45mph. I have to either have the foot off the gas pedal, or going faster. It won't let me go inbetween keeping a constant speed. It will only speed up or slow down. There is like a gap. I was thinking maybe there is slack in the cable or something like that because I can press the pedal and nothing will happen and then it engages and I speed up. I put my foot off the pedal a bit to keep a constant speed, and it will hop out of giving it gas. So its either speeding up, or slowing down because it stops giving gas. (Hard to explain) I cannot keep a constant speed
- The final problem is my fuel. The fuel is in excess. Whenever I give it WOT, there is a cloud of black smoke out the back of the motor. I never concluded what the problem was because there could be so many probabilities. But, the mpg is really low. I was thinking maybe dumping excess fuel from injectors, but someone told me to just get an adjustable fpr and that would fix it. I don't see how because the fpr that I have on is from the vx so wouldn't the current setup give less fuel?

By the way, when doing my swap, I took out the IACV and cleaned the mesh. Seems to be fine. Also, all the sensors are hooked up correctly, but I believe that my Heated O2 sensor is bad. Can't be for sure. Also, I have no intake as of right now, its just the filter on the throttle body. And, I have a breather on the valve cover where a vaccum line is suppose to be, so I have a couple extra hoses not hooked up b/c of no intake and the breather. Don't know what I should do with the vac lines.

That should do it, please help as this is damaging the reliability of my car.
Thanks,
