2012 Honda Fit sport automatic ticking noise from engine
 

Just wanted to share my experience with the ticking noise from my engine. Noticed the ticking noise one morning, and thought it was related to a belt issue, and my mechanic said it sounded like a normal Honda tick. About 4,000 miles later my engine light and VSC light went on, the car continued to drive without issue. Drove it directly to my mechanic, was due for an oil change anyway.
In the end, the ticking noise was related to spark plugs being loose and could be heard. Spark plug 2, 3, and 4 were loose and 1 was good. 1-4 spark plugs replaced, 2,3,4 coil packs were burnt, replaced all coil packs including 1 and a valve adjustment, valves were out of minor adjustment.

Purchased the fit used and I'm the 3rd owner, carfax showed spark plugs being replaced at 85,000, so I knew it would be time soon.
Fir Mileage is 152,700
Fit running smooth and the tick is no longer present.
Wanted to share it since I didn't see this experience posted in this forum.

Hope this helps someone else.
