I've been missing all the vital signs that I needed for love to work
Engine of a heart that would not start, had to jump it so much, it hurt
Every time I looked under the hood it was always a mystery
You pulled up in a rescue truck, showed up with a master key
And revved it up for me

My pulse was nearly gone 
I was almost in need of a defibrillator
I didn't know what went wrong
I had to shake it off but I got stuck
Oh my God, you turned all my loose strings
You're the love innovator that brings all the right tools
You know what to do
Fine tune
Fine tune

You started tweaking on a little knob that I didn't even know was there
Kissing on my wrist all the way to my neck, running your fingers through my hair
I felt like I was dizzy and I didn't think I could drive
You flipped a switch, hot wired my gears, yeah, you put me in line
And now I'm running right

My pulse was nearly gone 
I was almost in need of a defibrillator
I didn't know what went wrong
I had to shake it off but I got stuck
Oh my God, you turned all my loose strings
You're the love innovator that brings all the right tools
You know what to do
Fine tune
Fine tune
