Well, I kind of have to live with that noise for now, because I use my car EVERYDAY.
About contacting Andy, haven't had a chance, as I was sick last week, and when I got better, I had a car detailed, then had exams and had to study, then had to fix computers lol. By the time I finish its late, when I get home I am tired and haven't had a chance to call yet.
I will probably call tomorrow and ask for a new set to be delivered to my house. Thing is I don't like that I have to pay for both shippings back and forth, so I don't mind paying the one when I send the old coils. Why I don't like paying? Because its not my fault that I got faulty rear coils.
As for your advices, I appreciate, but I don't want to go that far lol. I am not that type
Also, refund is not available/possible, only fix. I guess I will try to call tomorrow, if I won't forget and will have time and let you know how it goes.
Thanks for help and concern though
