Fast idle solenoid

[Pclancy]

I'd like to experiment (?) with a fast idle solenoid to see how that reduces or eliminates the trembling my 400 motor (with an Edelbrock 1406 carb) demonstrates at idle with the A/C on. I have a 77 Newport.

The trembling is just enough to be annoying and noticeable. This girl deserves better. There is no trembling without the A/C. I have the original compressor and don't want to spend the big bucks to replace it. The AC--converted to R-134A--works well, although it doesn't get super cold. Around 58F.

Can someone help me research the correct part number from Summit? Do I need a special bracket? I want to connect the solenoid so that it only steps up the idle with the AC on. And not by much.

Thanks Everyone!

Peter

Check out Summit they have a line of them.

This is for the 8059 carb. Not sure if the bracket is correct but they should be able to help you. It will help.

Many thanks!

Before you spend the big bucks.... what is the idle rpm with a/c on??? And what is it off?

When I converted to a lightweight Sanden, I couldn't believe how much smoother it idled.
I've had cars with the hi-idle solenoid. Hated them. Torque converter hated them, too. Reconsider dumping the R2.

The solenoid was not cheap, like about $150. But it has made a big difference in how she idles with the a/c on. I was afraid that she would idle too high, but no, she just purrs at all times now. I'm a happy camper.

That’s great news I was pretty sure it would. Where did you take the power from.

From the A/C clutch.

From the A/C clutch.

Perfect that would be my recommendation. What rpm did you set it too.

Let me get back to you on that; need to ask my mechanic.
