Weber Issue - Not returning to full Idle

[thornleyjacob]

Seems to be a lot of different issues with idle these days; mine seems to be different.

• EA81
• New Weber 32/36 DGEV
• New Throttle Cable

• Car runs fine while cold.
• During hot weather, or once the engine is warm, the throttle linkage does not return to 0.
• Checked accelerator pedal and pedal return spring; no play here when this happens.
• Played with throttle cable and cable housing while not back to 0; does not reset.
• Just touching the throttle linkage will make it return to 0; I visually confirmed that the linkage itself moves back to 0.

I've taken the linkage apart, cleaned it up (even though it was clean), and give it a bit of grease. The only thing I can think of is that maybe I am tightening the bolt back down too tight? I only take it to the point that it doesn't wobble anymore. Really am stumped here.

Had issue of the barrel on the end of the accelerator cable catching on part of the choke linkage of the Weber.

 

I was using the Hitachi cable attachment on the Weber.

Fixed it by adding a couple of washers in behind that plate..

 

So, I would take a good look at that area of yours.

You didn't mention a throttle return spring.

Mine does the same thing when hot. I have not added a return spring yet. I'm not sure what causes it but it happens when its really hot and I'm on a long road trip. Spring should cure what ails your subie.

Thanks - will be taking a closer look at it this weekend and seeing if I can cure the issue completely.
