For about a week or so, I had noticed a scratching sort of noise coming
from somewhere under the hood, but was unable to pin-point its location.
There were no changes in engine performance or behavior. One morning,
I was sitting at a stoplight, the engine stumbled very hard, and almost
cut off. The Check-Engine light came on, and idle RPM level returned to
normal. (I also noticed the scratching noise had stopped) Upon trying
to accelerate, I noticed the car would not rev any higher than
3,500RPMs. (This is a classic symptom of the auxillary fuel injector
not working) I checked the ECU and the LED was blinking 16 times, which
corresponds to the "Fuel Injector or Fuel Injector Circuit". I called a
few mechanics that were supposed to be "Honda specialists" and they all
told me to change the throttle body because the Throttle Position Sensor
had gone bad and that is what was causing the Check Engine light to come
on and making the Fuel Injector stop working. I bought a throttle body
from Beaver's Honda (junk yard) for $65 and changed it myself. Now,
when I crank it up, it idles at almost 2,000RPMs. The idle adjuster
screw is all the way out, so that's not causing the high idle speed.
When the accelerator is pressed, I can hear the engine suck in a lot of
air, but instead of revving up, it bogs down, and then back-fires
through the intake. Aside from changing the throttle body, I have not
changed any other parts.

I took my car to a highly recommended mechanic and he told me that the
problem was being caused by 2 things: #1. My distributor is not working
properly. #2. Due to #1, the ECU is throwing code #16. So, he recommended
replacing the distributor and the ECU. I've gotten a few responses to my
original post; what do you guys think? (If you're just joining us, my car
is a 1990 Civic LX, 5-speed, 1.5L Dual-Point Fuel Injection; D15B2)
Thanx again! ;-)
P.S. By distributor, he means the whole thing, not just the cap.
