08 335i Start up inconsistencies
When I go out to start up my car after it has been sitting for a while, I notice sometimes that it starts up differently. Sometimes it starts up how I would assume a normal start up should sound, and then others sound as if its starts up weak and putters a little bit until I give it a touch of gas, as if to get the engine into rhythm. Also, I notice that my break is tightened at times when this happens, and its becomes much more difficult to depress the break pedal. Any ideas what these are symptoms of?
