Hi all, when I start my car when the engine is cold and the revs drop below 1000rpm to idle (600rpm) the car feels like its miss firing and is not happy. When she is warm she runs sweet as a nut. I have replaced all 4 coils but this hasn't cleared it. I just wondered if anybody has had the same problem or knows what it could be?? Thanks in advance Aaron

Mine does and always has idled at around 650-700..

You can manipulate that

The ICV may need to warm up to work which is not correct. Get that cleaned first and go from there :)

What do you mean Darren? Manipulate it? I thought it was okay for a low idle?

It is. I'm just saying, you can change that when you want by adjusting the throttle cable. In context to what Aaron is saying, to manipulate his idle there is more to it as something is at fault

+1 t Daz, But check airfilter, or give it a full service, basically check all fluid levels, just give the whole car a good going over making sure everything basic is correct then go from there< airflow meters can do this but normally would also run rough as well

      X3 2.0 automatic

      hi , I had very similar problem a while back, and after a lot of testing with vista, it turned out to be a front R/H wheel , speed/wheel sensor. when it all was happing lots of codes were coming up gearbox, diff front and back, transever box,plus many more, didn't look good, but there was one code that repeatedly came up at the top of the list, at this point it was becoming undriveable ,it just didn't seem that a wheel sensor could cause all these codes. So I went got two wheel speed sensor, replaced driver side front, the problem never came back, the sensor controls so many systems ,cleared all codes, happy days, I could have pulled the car apart for nothing, and got nowhere, except an empty wallet. hope this helps you or someone.

      105C thermostat replacement

      As I understand the wiring diagrams and operation Item 9 on the thermostat housing is the sensor which sends its signal to the ECU for interpretation with information from the map sensor. Information from item 12 (1st drawing ) is also used to provide average temp across the cooling system. As far as I am aware the Thermostst is independent of the sensors and operated by expanding wax material internally

      BMW 318i boot locked can’t get into

      Errr not clear here Donald Plastic "L's" with short rubber hoses ??? Distilled water/Ionised water should only be used in an old style lead acid battery. The Rad and engine coolining system should be filled with the correct coolant mix to prevent cavitation and the danger of freezing in low temps. Coolant should be part of the cars regular maintenance and changed every 3 years or so. At that time all hoses and connectors should be inspected and changed where necessary to keep everything in tip top condition. Changing parts can cause as many problems as you may think your solving

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.
