Hello, I have a 1990 prelude 4ws 2.1 si. The problem I am having is if I have to stop fast or if I am going down a steep grade and start to stop the motor will die, if I am going up hill and stop quickly the motor will not die. I have replaced the fuel fillters and the fuel pump, the last time it died when I was leaving the house ( drive way is very steep) it died at the end of the drive way and would not start, had about 1/4 tank of fuel, added about a gallon of fuel and it started right up, started backing up the drive way and it tried to die but kept running, runs fine when going up the drive way. I read that the main relay might be the problem but i can feel it pull in and the can hear the fuel pump running, very strange. Has anyone seen this in the past?
