Engine misfiring in cylinder #2 while in motion and stationary on at least city streets. Excess fuel in catalytic converter causes engine to reduce power output. Car becomes extremely difficult to accelerate, potentially causing accidents when crossing through intersections. Upon engine inspection the #2 spark plug unthreaded itself at least three turns before destroying remaining 9 threads and dislodging from the head catching into the coil pack. Car has approximately 60K miles, spark plugs never touched outside of Honda factory, and service interval calls for spark plug replacement in the 100K region.
Upon realizing declining fuel economy and an engine misfire warning I replaced my plugs noting that cylinder 2 plug required almost no removal torque and was very fouled (pictures available). Less than a 4 months later, engine light came on, diagnosed within minutes as misfire, before I could return home, engine ejected plug and started a fire in the engine compartment. I was able to extinguish the fire with snow (and 2 cans of diet soda) before the car was consumed but I suffered burns on the hands from dripping melted plastic.
Today 06/08/2015 I got my car back from my local mechanic after major service @93000 miles. He told me 3 out of 4 spark plugs in the engine were loose(they were only hand-tight): One was secured, one was almost out of the engine and blacked out, and two of them were half way in. That correlated an incidence August 2014 when I was driving on the freeway. My Honda Fit suddenly lost power to no more than 20mph. I got it towed to dealer and they told me one of the spark plug was completely blown out of the engine, along with the ignition coil. The mileage back then was about 80,000 and I never had any major service nor even opening up the engine block by anyone. Spark plug service is 100,000 mile interval and I did only oil change in last 3 years before the incidence. Dealer (diamond Honda, city of industry, ca) had the engine head re-threaded and agreed to pay 70% of the total cost. However I found out today that apparently all spark plugs were loose even when the car left the factory! the dealer did not take a close look when they serviced it last year. That is why one plug is still intacted and secured in the head while other 3 were only hand-tighten. Please investigate or inform other Fit owner that this year or probably other year Fits have hand-tighten spark plugs that can lead to sudden loss of power. My incidence last year almost got me into serious accident while I was on California crazy highway.

After driving 20 miles through traffic with 1/2 tank gas and radiator temperature ok, no warning lights showing: Turned right at intersection and lost all engine power (no throttle response), then all lights (headlights and dash). Steering became stiff. We think cd player stayed on. Luckily no nearby traffic and enough momentum to pull into nearby parking lot. Put car in park, turned key off and removed it. Replaced key and car started with lights ok. We've had this car for 1500 miles and this is the first time it's done this.
