Hey guys, I recently ran into an issue with my car. Two days ago I had to jump my car. Since then it's started just fine. I got my battery tested at O'Reilly's and it tested good. I went to start my car after reinstalling battery and left the power cord with the fuse unplugged. Car wouldn't start. Plugged it in. Car started. Unhooked Ground and it still ran. Unhooking the power w/fuse it turned off. My acceleration has dropped tremendously but my top speed seemed to increase. Normally I could run my car up to 5k rpm and I'd be to 60 going into 4th gear. Now it barely wants to do that. Along with that, my brakes are sticking. Anyone have any solutions? Thanks!
