Hi folks, recently picked up a wee honda logo with an idle bounce at running temp. Wana replace the intace air control valve but having problems sourcing 1.

 

Any ideas or links would be appreciated. 

I would look for a vacuum leak first as this can cause the issue you are experiencing

Sorted the issue by cleaning the throttle body with some wd40 on a rag. 

 

The eml lights came on and some black smoke which I'm guessing is the oil burning from the cleaning. 

 

My new issue is the rad fan not kicking in. The motors fine as I did a direct feed from battery. Fuse is good and I swapped over relays with the horn which works. The temp gauge sits at halfway at running temp, I'll probably take out the thermostat next to see if that's working... Then it's either the temp sensor or the loom itself. Any other ideas? 

you could always wire in a temporary switch or variable resistor to power the fan to test it or even run it as an over ride
