I have a Sport slightly below 90K miles. Starting this past weekend, my Fit would begin to stutter while idle. If I am at a stop light or waiting to pull out, my car would stutter for a few seconds before going back to normal. This does not occur when I am accelerating or actually driving.

After reading this thread, I brought it into the local Honda dealership and pointed out that it could be the ignition coils. They blew me off stating that if the check engine light wasn't on, it's not the ignition coils. Two days later after running diagnostics and test driving the car, they found no issues.

What happens on my way home from the dealership? The stutter continues.

Just to point out:

• I've had the battery replaced within the past year.
• All proper maintenance has been done on the car.

If the problem is the ignition coils, what's the easiest way to get them replaced in regards to someone who has never worked on a car before?

 

Ignition coils are actually easy to replace, there's just one bolt holding them down actually. If it's your ignition coils, one major way to diagnose it would be with turning on your A/C and see if you get a misfire symptom or not. If you need to warm up the car and when you stop at a stop light/sign the car stalls then it's your valves actually.

 

The issue occurs if the A/C is running or not. If that's the case, a valve adjustment should solve the problem?

A great way to show the issue as I discovered the other night with my stepdad is when I switch the car from neutral to drive. If I sit the car in neutral for a minute or two and then switch the gear to drive, the stutter occurs right away.

 

I'm a little late to the party here but I was doing some searching for my current issue and came across this (unrelated.) when I got my 07 fit used a few years back with 61,000 miles on it I had this same issue. When I took it for a test drive when I was stopped I felt the stutter I just chalked it up to the AC. A couple weeks later after I had purchased it the stutter got worse and the engine light was coming on. Took it back to the dealer I got it from and they told me to take it to Honda. Honda adjusted the valves and said the problem was still there. Replaced the coil packs and that fixed it. They were nice enough to throw those in for free even though I was the 2nd owner and it was 1000 miles outside the warranty and the dealer I got the car from reimbursed me for Hondas charge for adjusting the valves.

 

Sounds like some nice dealerships, glad they fixed your problem!

 

I am glad to hear you got your issue fixed.

I just need to figure out where to take mine to get my problem solved since my local dealership doesn't want to help me.

 

You're from Vegas too? One of the few FF'ers from Vegas on this forum.

Which dealership do you go to, Honda West or Findlay? I've found Honda West better than Findlay.

 

Honda West.

I sent Honda West an email from my experience and this is the BS response I got back:

"I am sorry that you felt you were treated poorly on your last visit. I would like to change that and I will make sure that you will be treated fairly and respectfully if you choose to come back

I would like to look at your vehicle again for you. I will do this at no charge as far as diagnoses. I will say that I do not want to just replace coils because the internet community states that’s the problem to the concern. What would happen if we replace the coils at the cost of over $600.00 and you still experienced the same concerns. If you can leave your vehicle here for 1 full day. I will address your concern. Please get back with me when you have a chance."

$600 to chance the coils? Thanks, but no thanks.

I'm headed to an independent mechanic based upon recommendations from co-workers.

EDIT: Scratch that. After reading all the various other threads in this forum, I am going to do it myself with the help of my stepdad. Just purchased NGK (6774) IZFR6K13 Laser Iridium Spark Plugs from Amazon alongside HITACHI IGC0053 coils from RockAuto.

 

I wanted to comment on this even though this is quite an old thread. It's still relevant. I've had two "07 Fit Sports. The first developed the stutter at about 90K miles. It turned out to be valve adjustment. The second developed the misfire at about 59K miles. The difference between the two is that the first was mostly noticeable at idle or low speeds and tended to be worse when the engine was warm. The second one was fine at idle was worse at speed, or when the AC was on. I just tried the grease fix on the coils and the stutter has disappeared, at least for the time being. If it reappears, I will spring for new coils. They are currently about $50 a pop at Rock Auto for the OEM parts. I should mention that I didn't quite understand Xcentrick,s description. I applied dielectric grease to the grooves at the top of the coil where it meets the long tube, and on the inside of boot where it meets the sparkplug. I also added some in the groove that seals against the ridge in the head, however, in retrospect I don't know what that will accomplish. I hope this helps someone else with their diagnosis.

 

When the coils age out, the grease is a bandaid, you've got micro crack in the plastic and rubber, there are some internal electronic parts as well in the coil that age. The packs are in the hottest part of the engine bay and bake out. I suspect if you could correlate the driving style, environment etc, that in city low speed traffic stop and go ages them out faster than a guy driving the freeway getting better air flow through the engine bay, outside temp plays as well. This problem is not unique to the fit, Toyota MR2's, FX anything with eh toyota twin cam had the same issues, porsches, bmws, audi etc have also all had issues.

The grease fills the cracks and helps insulate.. But they fail eventually.

 

Similar issue on my 2007 Honda Fit Base model. At approx 270,000 miles, the engine would stutter under load / acceleration. Error code showed misfire on three cylinders. The actual problem was a bad coil on cylinder three. I replaced all four coils and plugs and now its runs great. I bought a new set of four aftermarket coils off ebay for $60 total. Sounded to cheap to be true but so far so good.

 

I have 07 Honda Fit with 90k miles.
I had the same problem as many of you posted here. I just put new ignition coil and fix everything. My Fit is driving great again.
buying four ignition coil will cost about $200.
BTW when you change the four coils change the spark plugs too it will cost you about $10 for four spark plugs
Changing the coils is very easy. The four coils are setting on top far back of the engine easy to reach.

 

The advice on this website is great! In summary, and what worked for me on my Fit at 90k miles that was running rough, is first check the coils and spark plugs (4 each). A diagnostic test easily tells you if one is defective (or just replace all of them - but don't buy cheap ones - I got a bad coil with a special low price for four on the Internet). The plugs and coils are pretty easy to replace (good videos on YouTube). If the plugs and coils are okay, have the valves adjusted, which it sounds like needs to be done on all high mileage Honda Fits. It is not easy, and takes about 3 hours, so it is pricey to have done, but my Fit is running great now!
