Okay so about 7 months ago I purchased my first car at 17 years old and I chose it to be my 1990 Honda Civic hatchback, it gave me no problems at all, about 4 months ago it started to turn off while I drove it every once in a while, I changed my alternator, my battery and my fuel pump and recently it’s just gotten worst and turns off more frequently while driving and at lights, at first when it turned off my obd0 threw a code 14, I took out my air idle control valve and it looked kinda rusty, I cleaned it out good with brake cleaner and put it back and the code went away, I was driving it and noticed that when I drive And i put my car in neutral, my idle goes really low and sometimes it’ll go low then come back to idle or will just turn off, my car sometimes turns off while driving as well, yesterday I was at my gate at in neutral my car just turned off, then a code 16 came up, fuel injectors, but I don’t understand because I just put new oem ones in! Helppp!!!!
