Thanks to the response I got in my last post I found the pcv valve and the tube that is connected to the crankcase ventilation, and I went to a honda dealer in kingman and he said he could not tell me what the part was called but he was looking at it on his computer. Anyways I still cant get the car to hold an idle? I've been through the fuel system back and forth the carb's vacuum lines and the only thing I can think of is maybe a throttle positioning sensor or something with the choke. If anyone has any suggestion it would really be appreciated, and thanks in advance. If it's any help if replaced: plugs, wires, cap, rotor, egr, pcv and (hose), o2 sensor, Idle Air intake Control. THANKS AGAIN!

Hi vewdew,

Did you check the fuel cut relay and idling circuit?

What Idle Air Intake control are you refering to?

Did you test for vacumn leaks?

Is the choke fully opened when warmed up?

For one it wont stay running to check for vacuum test/ or get warm to check idleing choke position, I switched the TPS located on the back of the carb that leads to an electrical circut. But could you be a little more specific about the parts you were refering too?

Sorry, I made a mistake about the fuel cut relay, it should be fuel cut solenoid located on the carb nearest the firewall.

It is a solenoid that if it does not work, will cut fuel supply for the idling circuit. Solenoid is located next to throttle adjust screw.

Disconnect the wire and apply battery voltage, it should click.

The idling circuit is the circuit inside the carb for fuel and air mixture to be drawn into manifold during idling.

The feedback carb system would control the idling circuit as well but the throttl position sensore seldom gives any problem. You would need to check the ECU under the seat.
