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. [End original message]**UPDATE**
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.
