Question about 2000 Mercedes-Benz E-Class

Open Question

E320, 2001 Model. Engine Revs stays revving high when driven cold.

I have a 2001 E320. When the car is started cold, the engine seem to stayed revved up to 2500-3000 rpm when you take off. It seems to rev up very high when driven for 1-2 mins. and satys on one low gear and does not change up. I stopped the car then re-started it, and the problem went away. It happened a couple of time on very cold mornings- 8-10C, When I sit there an ideling it for 1-2 mins before driving off. it seem to cut back to normal gears when you pick up speed, 20klm/hr, then 40klms/hrs and then60klms/hr. The gear seem to change fine.
I took it to my Merc specialist and he said the computer is showing it's storing some flat battery fauls in it's memory and this may be the cause. I left it with him overnight to see if this problem will re-occurr. It seem to be OK on warmer morning.. and doe snot seem to happen when the caris warm.
What are your thoughts.
Thank you..Andrew

    Mine is an 1999 E430 and when cold the low gears are held for about 10 minutes after starting!



    I know the intention is to promoite a quicker warm up, but that is only supposed to be a minute or so.



    Any solution anyone please?

1999 mercury villiager is revving up when put in park


does it stay at high idle, or come down. If it stays does it seem to coast faster than usual? If so, I'd say it sounds like an air intake gasket More info please

When i push in the clutch,the engine revs up.


If I am hearing you right, the engine revs ONLY when the clutch is depressed?
I would have to doubt that is what is really happening, tho. Is it possible that the engine is revving from the time that you start it, until the time that you shut it off?
This would be more likely, as depressing the clutch doesn't really have any effect on the engine, other than dis-engaging the drive-line...
IF it is revving at start up, see if it isn't only 'idling down' when the weight of the vehicle puts a load on the motor. In other words, does it idle down, or does it only SEEM like it is, because now it's pulling the car? Do you have to give it gas to go on a flat surface? If not, then it's still revving.
Then, if you decide that it's revving ALL the time, you will need to check it for vacuum-leaks or mis-adjusted linkages, or carburetor (throttle body, if it is injected).
Do yourself a favor and buy a Chilton or Haynes manual for your vehicle (at most any auto parts store), if you plan to keep it for a while. They will generally have troubleshooting sections, to help you eliminate variables until you find the actual issue. It's the best $20 you can spend!

When turn on the car in the morning, i accelerate and the revolutions up to 6,000rpm normal. In 3 minute when the car up the motor temperature to the normal operation, i accelerate and the revolutions up...


To begin with, if you are revving a cold engine to 6000 RPM, you are asking for a blown engine. Most OBD vehicles are equipped with a rev limiter that will cut off fuel at 3000 to 4000 rpm to prevent you from over-revving your engine and blowing it up. If yours is revving to 6000 RPM cold, then the rev limiter, for some reason is not working while it is cold. I have no explaination for this. The best thing I can tell you is to stop revving your engine so high when it is cold unless you really want to see what an engine looks like after is has gone off like a grenade.

My 1992 Chevy Blazer S 10 is revving really high when it starts


i have an s10 that would rev up high. i hooked up my scanner and it didn't give me much information, so i started researching. it took a while. i got my manual out and looked up all of the sensors in the fuel system. i even paid some web site $10 for help {wasred my $10} and they were no help. so i researched all of the sensors and found out their symptoms when they malfunctioned. the culprit turned out to be my water temp sensor. here is how it works, when you first start your engine the water is cold, the sensor sends out the information to the brain [warm me up] so your engine idles high to help reach operating temp quicker. when the sensor malfunctions it will send the wrong info to the brain [i'm cold] so the brain revs up the engine in an effort to get warm .i replaced the water temp sensor and the engine is back to normal.
