Question about 2005 Mini Cooper

1 Answer

Overheats at idle only, fine at speed or higher rev

When it starts to redline in traffic at a stop, I can get it to back down a bit by revving the engine up to 2k or so.

The coolant overflow bottle is full, but does that mean the level is okay?

Generally the bottle will give you some idea on level but if you have a cap on the radiator, that's the best place to check or fill. (only open cold) Also make sure that if you have an electric fan, that it's coming on when hot. Your computer also aids in cooling by advancing/retarding timing. It may not be.

My 2002 dodge durango hits 4000 RPMs and bounces between 3000 and 4000 RPMs when I am in park and have the throttle held down. I replaced the cam sensor and it is still doing it.


this is your rev limiter stopping you from over reving engine causing internal damage. this is normal on all new vehicles. Don't know what year they started this but it goes back at least 16 yrs

My automatic Corolla AE110 vibrates when i stop in gear but it stops as soon as i start moving or when i put it in neutral.What can i do? Please help


It seems that your engine is tuned to very low idle revs, hitting the low resonant frequency of the car at tickover. When in neutral or revving up (moving), the engine stops shaking.
You can have it tuned to be slightly higher so it won't idle so bad, but you'll lose a little bit of fuel efficiency in the bargain.
Alternatively, just shift to neutral - free and easy.

My 95 Honda Civic dx (revving up and down)


sounds like you might of blown a head or intake manifold gasket or cracked head. If it sounds like a rollercoaster going up the tracks or tractor sound. it's that. It's expensive repair. My advice if you dont know anyone cheap get another used car until you fix it or whatever your situation is. Also, it idles up and down because of the air escaping from the crack. If engine doesnt hold constant pressurethats whate happens. everything is to the T when working with vehicles. Plus redline dont matter, theres a cut off point, however because of the high rev you could of caused the over rev and blew a gasket or cracked the heads. Especially if you didnt have the proper fluids to keep the temperature down. Good Luck. Been there.

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.

1986 300zx revving problem


obviously play around with the idle. sometimes these old cars just need to be played around with for a bit. have the car idle a little bit higher than it should. also it might be taking in air at a constant rate

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

Check for a vaccum leak at the intake. With the engine at idle spray a bit of starting fluid to find it. You will hear the engine pick-up when you hit the spot. Change the necessary gasket. Hopefully this will solve your prob! Frankster016
