SOURCE: low/poor idle

Here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

SOURCE: the rev is going up & down on idle & when driving

have you checked your air inlet manifold for any leakages by spraying WD40 around each portall bolted to the cylinderhead gasket,check for vacuum air pipes deterioration.make sure the engine is running first ,then spray WD40 to check that the engine speed should increase.it sounds like your engine is haveing problems breathing due to heavy hydro carbons increasing./and your CO2% is dropping.

SOURCE: it idles fine when cold but when it starts to get warm it idles rough, you can feel it going up and down not badly but i can feel it and see it on the rev counter

Faulty idle air control valve. You could try and clean it with some carb cleaner, or replace it.

SOURCE: DSC and DTC failed on 36000 miles under 4 year BMW 120D

I think you should check ABS sensor ring on the rear wheels. This is known to come loose and cause this problem. Hopefully it's just that you not the entire hydraulic unit

Motor runs a little rough, idle goes up and down


From my experience with my wife's 97 Wrangler look at the intake manifold for 2 vacuum lines. They will be just under the throttlebody One of them is broken or has come loose. We had this problem several times, idle high, running eratic, until I put a smaller rubber hose on the fitting. Has run good since.

Bmw 320 d 150 bhp rough idling when starting cold


seems like theres a build up of carbon in the intake. you can try the pour in gas tank cleaners for fuel injection cars which you have and after 2 or 3 of those with 2 or 3 full tanks it will clean the injectors and the carbon out of the intake. And if you really want to get them cleaned up even better and stop all the rough idling, take the intake off yourself and clean all the black stuff off anywhere you see it. Thats the carbon build up. Especially on the butterfly valve area. It will not only run better for you but get better gas mileage as well.
