i have a manual 1995 honda civic ex coupe. i just replaced my distributor, spark plugs, spark plug wires, valve cover head gasket, and did an oil change. after when i replace those i test drove my car around my neighborhood and i heard popping noise coming from my engine and a loss of power so i drove home and tried to find out what was wrong and noticed my aftermarket air intake sounded different like it wasnt sucking air and the only time when it sucks air is when i press on the accelerator, and when idling it idles rough and about to stall. im not 100% sure but i think its either fuel filter, fuel pump, idle control valve, or my valve needs adjusting. i replaced fuel pump and fuel filter when i bought the car last month. but maybe the fuel pump or fuel filter got dirty? but anyways can someone whos experienced or went through this before help me out and tell me what i should do to fix this problem, thank you.

 

Check whether you installed the spark plug wires in the wrong firing order on the distributor cap.

Any CEL codes thrown?
