Starter

[Skskinner92]

I changed my starter on my 08 328i and am having a few problems. The car will start but it takes a few tries sometimes other times it starts right up. When its running it'll be fine then start to idle rough then die. It starts right back up however as soon as I press on gas unless I just floor it it dies again. It was also making a loud whine I guess is how I would describe the noise it was making. I have no idea where to start to fix this. This all started after replacing the starter
