Report "I have a 91 Honda Accord LX , my car stalled out on me and gave me a code 15. ive been researching the problem and i know it cant be the distributor because i replaced it with a aftermarket one 7 months and ago and i know the main relay is good because i hear the relay click and that was replaced about a year ago. I am not to sure if its a transmission problem. my D4 light doesnt work. so i dont know if its flashing and my "S" light isnt flashing. also my car does have a bit of a poor up shift and down shift at times. the car only stalls when i perform a power brake test. the car runs fine in park and rev the engine to 2000rpm. also the car does turn back on when i let the car cool down a bit. any thoughts?"
