Car Running Rough
Okay, asking for some help here guys!
So I changed my alternator, and I f'ed up because I must not screwed the electrical connector in incorrectly, because soon after starting my car, the engine shut off and there was a small cloud of white smoke. I took everything back apart and noticed a small burn on the alternator, and some of the plastic melted away. I took the alternator back to Auto Zone, and lucky for me the guy let me exchange it for a new one and charged my battery. Re-installed everything and made sure I screwed the metal connector in correctly this time. Started the car up, and everything seemed fine, but noticed the car seemed to run a bit rough. Tried driving it up the street and quickly turned around because I got almost no power. Somethings not right. Can someone help me and maybe point me to what I f'ed up and what I can do to fix it? I hope I didn't mess up my engine.
Could it be an issue with my spark plugs? Maybe thery got missed up with the car shutting off? I have a 2004 X5, V8 4.4
