View Full Version : Idle speed

10-26-2006, 10:19 AM
Had an unusual idle speed issue today. I usually idle around 800 when the car is cold, and then around 1100 when it gets warm. I pull into the office today and for some reason I'm idling at 1500. I goose the engine, and it comes back down, but then creeps back to 1500. Not sure what's going on there. I'll check it out tonight on the way home, but any thoughts on that?

you might try plugging off vacuum lines and brake booster line, and see if that takes the RPM back down, I had a bad break booster and that caused erratic idling

Damper oil. Checked it lately? I had the same thing happen. Found that the oil needed topping off. Did it. Fixed It.

Wish it was always that easy.

Hello Bill,

why do your un such a high idle speed, 900 to a 1000 is fine cold but 700 is better hot?
Anthony, that's strange, the damper oil has no function at steady speed conditions?

You might be right but its a good idea anyways to always check you damper oil level. I do a check of oil level, brake fluid, clutch fluid, damper oil and coolant everytime before I take the car out. Of course mine only goes out on sunny days and never in winter. Just my 2 cents worth even though my wife will only give me a penny for my thoughts. /ubbthreads/images/graemlins/cheers.gif

Howdy gang. Thanks for the posts. I'll check the oil level in the dampeners -- Haven't done that in several months. I've got a new servo, and haven't heard any of the hissing when they die, but I'll take a look anyway. Let's hope it's something minor. /ubbthreads/images/graemlins/cryin.gif

Definitely check vacuum lines. A loose connection can easily mess with idle speed.

Check that the small vacuum line below the carbs leading to the distributor is still connected, mine slips off sometimes and mirrors your problem when it does.
