Hello guys,

First Issue: So I'm having this problem with my AC kind of...okay so my AC works fine no problem the best cold air ever so this has happened to me about 3 times, I have my AC on and then turn it off and then my car turns off completely and shows all the start up dashboard lights? Then I have to put my car back in park and then start it up again and there is no problem with the start up. My question is why is my car turning off....? That is my first issue.

Second Issue: When I drive and stay or stay at the steady speed of about 40 mph my car starts to shake and putter some but when I go below or pass 40 mph the car is fine and this only happens sometimes. Why is that? I have no clue what it is, it only happens at the 40 mph mark.

Please guys help I really don't want anything bad to happen to my car!

 

Ground wire maybe, as in main ground or motor ground.

 

umm does anyone have any ideas or can anyone help me please?
