The pictures are from behind my S5 N/A TB.

--> Is everything identify correctly ?

--> My adjustment is off (suppose to be at 25°C) ?

--> What screw do I use to adjust it, the Cam or the Fast idle, and how do I know if it's really ok ?

--> Is the gap normal ?

I think I know what to do, I just want to be certain so I don't mess up things...

In other words, from what you see in my pictures, what should I do ???

 

It's not the water thermosensor.... but the water thermovalve !!!

 

Go read the FUEL seciton of the FSM. It explains how to do it.

The cam adjusting screw is used to set the *marks* on the cam. The temperature is supposed to be approx 77* when you do that.

AFTER you set the marks, you use the FAST IDLE SCREW to set the distance b/t the PRIMARY throttle valve (butterfly) and the wall of the throttle bore.

The OTHER screw was installed with putty to cover the area where a screwdriver could turn it. There is no set distance. That was done at the factory and should not have to be adjusted at all.

BUT, when you finally get the fast idle cam/screw etc all adjusted, what you can do is LIFT UPWARDS (towards the screws head) on that cam adjuting screw and you will notice the cam will come off the roller AND the linkage will move towards that OTHER screw. The linkage should just barely touch that OTHER screws end and there should be no gap.

Or put another way, once the engine is fully HOT, and the roller and cam have seperated, there should be no gap b/t the linkage and the OTHER screw.

OTHER SCREW being the one with the 8mm wrench size nut on it. Tiny screw.

The CAM ADJUSTING SCREW is the one who's end touches the thermowax piston.

And take special note that the ROLLER should spin on it's shaft. The ROLLER is what rides on the cam. See if there is a FLAT SPOT on the roller. If so, that means it's been frozen iin place and been riding on the cam which caused the flat spot on the roller.

 

I changed my throttle body because the springs were stock...

Adjuts it.... and so far so good. Never ran better !!!!

HAILERS, I hope you realize how much your help is appreciated.

Thanks.
