I am looking for suggestions on how to increase my idle temporarily after startup. I live in a cold climate. After startup, the engine idles too low and the truck feels like it is going to rattle apart unless I increase the rpms. The issue goes away after the engine is warm. Also, this isn't an issue during the summer.

Any ideas on a solution? I was thinking about possibly a pull cable. Other ideas?

If you agree with the cable, any suggestions on where to get one?

Also, I have a autometer tach installed that senses alternator rotation. Because of this, you must calibrate it. Is there a tool out there that will measure the RPM's that I can reference to set the tach?

Thanks in advance!

go to the boneyard and find an old Mopar with an idle increase solenoid. You can make a bracket for it and either engage it with a manual switch or hook it to the hot water switch or the KSB solenoid wire.

Like this one:

i bought an army surplus throttle cable from saturn surplus.then i welded a small piece of square stock to the foot pedal (gas pedal) linkage under the dash.drilled an 1/8 inch hole in the square stock and inserted the throttle cable thru the hole.that's it.worked well for years.

ohh whats the six pak in?

I found the picture on the "InterWeb".

Several GM cars also have the electric high-idle solenoid and are easily retrofitted to engage the throttle-lever on the VE.


Best is to install a locking throttle-cable that connects to the throttle-lever via a short length of small chain that goes slightly slack when the cable is not in use.

The chain allows normal un-hindered accelerator movement without binding the throttle-cable.

Best is a locking Vernier throttle-cable, although a simple locking throttle-cable is sufficient to the task.

Not the absolute most accurate method, but plenty close enough for our purposes :


The un-molested standard-issue VE injector-pump is governed at 2700-RPM.

Hold the engine wide open and note where the tach needle reads, then adjust accordingly.

Standard idle RPM is about 650-RPM; adjust accordingly.


This should get you in the ballpark.


You can also figure gear ratios, tire diameter, etc., do the math, and come up with whatever RPM the engine is turning at a given MPH --- 60-MPH is a good measuring stick; then, adjust the tach reading accordingly.



I feel that my alternator tach is fairly accurate.

In my truck, 3:55 rears, 5-speed Getrag, 1600-RPM = 55-MPH in 4th/DIRECT = 65-MPH in 5th/OD

I think a solenoid with a relay triggered by the ksb signal is an elegant solution, but a cable is the tried and true way to do it. We had a 64 dodge truck that had a throttle pull from the factory.

Thanks Guys for the very informative replies. I feel like a tool that I haven't responded sooner.

Thanks

No worries, these threads are a form of therapy and they take on a life of their own!

My 90 has a factory throttle cable very similar to the one cseby fabbed up.

Did they put these on the intercooled trucks?

Just in case you have not seen this option.

It is kind of hard to see the actual mechanics of how the idle is increased in the drawing.

If anyone has this option and could take a few pictures of Item #6 in the picture it would be appreciated.

If you have cruise control, there is a current thread in the "89 -93 non powertrain" forum at cumminsforum.com on how to install two simple switches into your cruise servo wiring to use the servo to bump up the idle speed at a stand still. It looks real simple to do.
