I have a 90 Civic Hatchback i got a D16Z6 put in and sometimes it woudl run funky seems like it doesn't get enough gas at certain RPM between 2 and 4 its random between them numbers it was throwning codes 16 and 43 (Fuel Injectors and Fuel System) Searched and said Main Relay i just got a main relay a few days ago and put it on at least the car startes all the time for me. When it acts up i can turn the car off and then turn it back on and it will run fine my injectors are in great condition anybody have any ideas for me to check i am about to put a Walbro fuel pump on to see if that helps.

Thanks For The Help
