what is the problem the fuel pump or ????????

and sometime i get good old code #7 tps sometimes and then sometimes i get code #4 iacv

i own a 99 civic hatch with a jdm b18c p72 motor with a obd2 to obd1 on it and then i have p61 ecu with a tuned hondata s200 on it


help me please

 

I guess the first thing i would check is the fuel filter. When was the last time it was replaced?
Also testing the fuel pump to see if its good or not is not a very hard thing to do, so you could look into that if you think its bad. If the pump seems ok id definitely guess the fuel filter then.

 

yeah i was planning on changing it so ill do that and then i check the pump as well thanks
