Hi,


One of the most common Mercedes 126 repair challenges is a high idle. Generally, the culprit is electronic, but sometimes a simple mechanical adjustment of the throttle linkage will solve the problem. Of course, older engines are likely to suffer from intake vacuum leaks of varying severity, and these also can cause idle problems. To check out few ideas of adjusting the throttle or anyother mechanical issues please read the ideas mentioned in the bellow link:

Thank You for contacting fixya.com

What is the factory Idle rpm for 22re efi engine


I've seen from 500 to 1500 RPM in all the manuals I've been through, depending on the year and application (truck/car). In personal experience, 650-800 RPM is acceptable warm operation range. This will also depend on elevation. Will go up to 1200-1500 RPM for cold starting. I live at about 2000ft and my '86 Pickup 22RE idles at 725-750 like a top after about a 3-4 min warm up @ 1250 RPM if it's cold (<45ish).

The idle on my '90 4runner 3.0 fluctuates and idles at 1500 rpm any ideas?


You should remove inspect and clean the idle control valve on the throttle body. This can become clogged over time, or the motor itself can become worn and may need replacing.

Volvo v40 2000nx reg 1.8 NON gdi engine constant high rpm can having no thermostat cause constant high rpm or can a briken lambda sensor cause high rpm cleaned all throttle body cleaned idle valve checked...


Yes, having no thermostat can cause the car to run fast as it will still be set in it's "warm up" mode and will be injecting a richer mixture of fuel/air into the cylinders. There may be an additional cold start injector that just works while the engine is cold. You will probably use more fuel like this. It's not a great idea to run with no thermostat anyway because you get uneven hot and cold spots around the engine which is bad for it. Cheers

Idle is high unless I tap the gas pedal


To me this sounds like the return spring on the carby has lost its strengh or your carburator needs a good clean as the throtle linkages could be dirty. I hope this helps.

Too fast idle running speed.


Typical idle for this motor is right around the amount you have described. Check to see if any check engine lights are on, or if the ABS light is on. A typical issue with this motor is the OVP relay that when not operating properly causes the engine to rev much too high (~1500-2000). Also do your revs drop significantly when you put the car into gear? If not then there really isnt an issue. When the motor is idling too high and you stick it into gear the car will typically lurch really hard.
