I have a 87 prelude and its having problems bogging down when you go into the throttle. I replaced the fuel pump,fuel filter,main relay,and fuel pressure regulator,also the ECT sensor. Anyone have an idea what it might be.

 

plugged cat?

 

Didn't think about that. cause it goes fine and everytime you give it throttle it almost like it cuts out then goes.

 

Secondary ignition.

 

try to reset the ecu. could be the knock sensor crapping out too..

 

I dont think the 87 has a knock sensor. A failed knock sensor wont cause a bogging down issue. Check the secondary ignition. Cap, rotor, plugs, and wires.

 

tune up

 

How about the injectors being clogged. I've done all but the secondary ignition
