Hi i have 2 main issues with my 2000 Maxima when I first got it (a gift from my exboyfriend &#128580 it didn’t go past 20 miles and forget about it going up anything with even the slightest incline it sounded like it was about to die if it did go on anything that wasn’t a flat surface I changed out the transmission fluid about 6-7 times and got a new filter for it due to the fluid in there was so thick and nasty it looked like chocolate milk mixed with motor oil that helped a lot but one day it just wouldn’t start so I hit the starter and it started but it’s now slower than it was at first that’s the first problem the second problem is someone tried to steal the car unsuccessfully by taking out the ignition cylinder everything looks to have been left behind but I have to use a flat head to try and start it which it doesn’t anymore it cranks and sounds like it’s about to start but doesn’t I have a brand new battery new terminals full tank of gas I’ve even tried to jump it starter fluid and nothing any suggestions help is appreciated thank you please don’t be mean
