No, find the mechanic first and then with his agreement purchase the parts...I am going to buy parts from Amazon and find my own mechanic -- I'm doing the right thing here, yes?
Since you are NOT a DIY'er you need an established relationship between YOUR mechanic and yourself. You don't tell your Doctor how to fix "you" nor do you tell your mechanic how to fix your car.
A good mechanic is hard to find these days. The investment in tools is horrendous and the OEM no longer freely dispenses information that may be used against them in warrantee work etc. The public balks at $100 an hour labor rates when in reality the guy doing the job is lucky to get $25 of that amount.
I could rant on for a while but I won't.
I suggest taking it to the Acura dealer and just stand firm on what you want fixed. Do your homework and find out the best dealer in your area.
In the meantime start looking for a mechanic and building a relationship that works for both of you.
