Hey all, I have a 1987 honda civic hb si that has recently begun a baffling problem.<br><br>Whenever I step on my brakes, the PGM-Fi light flashes on and the stereo shuts off and back on again, but the car doesnt act weird-just keeps on running fine. The stereo keeps its settings.. This only happens once in awhile, and only when I step on the brakes. The computer on the floor doesnt flash any lights when the pgm-fi light comes on, and the pgm-fi light flashes on and then goes off again.<br><br>I'm baffled, so is my mechanic. Anyone have any ideas?<br><br>thanks<br>Cat

Sounds like a computer problem. The bad thing is, and I own a 90 model LX by the way, that you will most likely have to deal with a dealer mechanic. Honda loves those computers and anything electrical. It most likely is within the circuit dealing with the signal from the brake pedal touching the "button" that makes the lights come on in the rear. Confusing wording I know, but, think about it. When you hit the brakes the lights come on, and you have problems. The only way I can think to remedy this is by getting the computer parts looked at, but first have someone inspect your wiring on that circuit. there may be a break, or ground--grounds happen at odd times, or it may be just be the universe, something small, or something huge. The only way to fix this is by thinking logically and asking people who know Hondas
