When I don't use my LR3 for a day or two I will get in it and the startup will be rough. To be more specific, it will fire up and the RMP's sail up fast like any normal start up and then the car will want to die. It will flutter around 0-200 RPM's wanting to shut off then just start to idle as normal. Then for the rest of the day and everyday after its fine, BUT if I DON'T drive it for a few days it's first start is like this..... Any suggestions...? Thanks
