I have a 2012 fit sport that I use for my business. In a year I've put right around 45,000 miles on it. Up until recently it has been an outstanding car. Lately, however, it intermittently loses power for a few seconds. It happens turning right, left, highway cruising speed with cruise control on (it disengages the cruise when it happens), hot, cold, etc. No check engine light has ever come on. It never stalls, but sure feels like it is about to, slowing way down. I have to let off the throttle, flutter it, or floor it to get the power back. The dealer spent six hours trying to diagnose what was happening, driving it with their laptop hooked up, and nothing registered for them when the car lost power. All data was spot on normal. They don’t have a clue. There’s no jumping out into traffic anymore, and interstate driving becomes interesting when the car begins to dramatically slow down on its own. I’ve read that replacing each coil assembly plug top might resolve it. Does anyone have any experience with this? Thanks.

 

99% this is coil packs. Mine GD did this over 2 years before I finally just replaced them out right. No CEL, no codes, NOTHING on my live feed from a FlashPro.

Finally pulled them at 76K when the CEL started flashing during the mis fires and they were BAD:


And the misfires and drastically eroded the electrodes on all 4 plugs, the gaps were HUGE and over 0.75 >.<

 

^^^ what he said. Seems odd at 45k to need to be replaced, but there have been stranger things to happen

 

Perfect. Thanks so much for the info. So now do I go back with OEM or are higher quality units available? Looked at Okada, Standard Motor Products, Denso, Beck/Arnley. Is there a reliable, gold standard, coil pack replacement? Thanks for the help.

I haven't had to change mine yet so I'm not sure.. maybe someone whose changed theirs can chime in? I'd recommend the OEM or Denso ones if I had to choose

 

Thanks. The Fit loses power enough to be really dangerous, so I think I'm going to change them out in the next week or so.

 

save some money and see about tapping the ground strap closer to tip

spark gaps increase with use and can cause coil failures since its trying so hard to make it jump the gap

hondas coils last plenty long if you are up to checking your sparkplug gap every 20-30k miles

same coils with slightly different housings are used on other hondas without issue

those 2 coils look VERY much like they were being overworked

 

Thanks. Will try this first.

 

Remember that if you need new spark plugs, a set of IK22's from Denso are $32 shipped on ebay

I think the NGK's that fit are better in my opinion (im biased as hell, I love NGK lol) are a tad more expensive on ebay then the Denso's
