Hey John,
I don't know if you happened to read my post back in July, but anyway, give this a try. Try re-gapping your plugs to .035" (instead of at factory specs). I closed the gap on my plugs over 3 months ago, and the stutter has not returned. FYI, I haven't noticed a drop in gas mileage, and the performance has not suffered. I have over 83,000 miles on the original OEM plugs (and coil packs). When you have the time, give it a try. It won't cost you anything but 30 minutes of your time. BTW, my Fit is an '07 GD3 5AT if that makes any difference.

I posted the same problem in another post regarding OBDII code P0303, 3rd cylinder misfire. So far I changed the plugs with new OEM ones (I think they're iridium plugs - costs about $6 each), but CEL (MID) came back on with same code. I switched the coils from cylinder 2 and 3 to see if code spits out a different code. So far, CEL hasn't returned. I'll post a follow up later.

We now have had a case of 'stuttering' honda. It was the coil. Switching coil ran the code from the former cylinder 0303 to the switched one 0304) after erasing. Before erasing got both 0303 and 0304 due to memorized 'defects'.. Replacing the coil and spark plugs while we were at it doused the OBD signals. All fine.
Based on the posts here it might be a good idea to purchase an OBD reader for $60 or so from Advance Auto or Amazon to keep up with this.

Today I was merging from one highway to another, as I accelerated to merge the car stuttered horribly and the engine light flashed three or four times. I was figuring out how I was going to make it to the shoulder when it calmed down and the light went off. I continued to get a few small stutters, but nothing huge. On the way home as I was accelerating to get on the highway I got another major stutter and the check engine light is now on all the time, even after restarting the engine. Back to the dealership I guess.

If I was you I'd follow Mahout's advice and get a code reader..... I have owned one for years and it has saved me a lot of time, money and worry that I can do with out.... I have always been able to find the cause and reason the CEL comes on and then the solution to turn it off and keep it from occurring again.... It would be great if there was a code reader to diagnose and solution malfunctions of a lot of people that I have had to deal with in real life situations.

BTW just how much is a coil cost? Multiply that times 4... and replacing all of the plugs under 105K...
My 200 Accord has all original plugs, coils etc... no problem
I have all of the gaskets, plugs, timing belt, water pump etc and the first tune up (you know by the book: 105K) is still going to cost me > $550.00 Ouch!

I have a code reader and it does not read any out-code. Therefore am I to assume - you know that good old ass u me joke - that everything is all right? Diagnostics at the dealer may cost me... $150.00 and how much is the cost of plugs and/or coils?? Just thinking.
My stutter has come back but not as bad before I changed the battery.
I was told that this problem is just with the first generation of Fit 2006 thru 2008... is this true?

I have a 2009 Fit M/T with 2K miles. My car is making an intermittent "tuh, tuh". It might be one, two, three or however many or none at all. It is concerning but I only hear the sound, I can feel nothing changing about the engine. I believe the sound happens only underway, I have not noticed it at a stop.
Also, the first tank of fuel checked at thirty-three miles per gallon and the MPG gauge said greater than thirty-eight. Why the discrepancy?
The dealer blames it on a solenoid in the evaporative emmissions cannister, since the sound is emmanating from the rear of the car.
Any ideas, anyone?

The stutter in mine (and I'm assuming others) is not a tuh tuh that you can just hear, its a stutter like someone is hitting a kill switch for a very short period of time. Very definitely can be felt.

Follow up with the cylinder 2 and 3 coil switch, but still get the same misfire code on 3rd cylinder.

Luckily I have another '09 Fit with over 100k miles without stutter issues, so I was able to swap all 4 coils between the 2 cars. As posted earlier, I also replaced all 4 plugs with brand new ones, but still get OBD code P0303 after 3 weeks. I have erased the code many times, but the CEL still toggles on and off intermittently - more on than off. There was no stuttering problem the 1st 50k miles on this car with no CEL.

Basically, I have ruled out the coil and spark plug to be the problem, because I still get code P0303, 3rd cylinder misfire, after the plugs and coils were changed out. My problem must be either in the electrical wiring before the plug or ECU malfunction. I'm going to try to clean the contacts on the 3rd cylinder coil connector with rubbing alcohol and see if the CEL goes away. I'll post a follow up.

How are the coil packs grounded (I haven't looked at mine nor have I seen wiring diagrams)? Obviously the hot side goes to the plug but there should be a grounded side as well. There could be corrosion on the electrical connections which limit current flow to the pack.

The shop had my car for three days now. They had previously replaced 2 out of four of the coil packs, which seemed to solve the stutter for two weeks or so. After spending a lot of time diagnosing and consulting with Honda, they did two things with my car this time:

- replace the other two coil packs (so now I have four new coil packs)
- high pressure clean out of the fuel delivery system

They suggested that dirty fuel might be causing the problem. While I can understand why they might be saying that, I buy gas from a couple of different stations, and I fill my Odyssey from the same sources with no issues.

They did a 130 mile(!) test drive and said there were no issues. Despite the fact that my car is well past the warranty (74K miles), Honda continues to authorize this work being done for free.

I'll update further after I get some miles on myself.

Hi Jisch..

I was one of the very first ones to experience this a while back ( more than 1 year ago now and at the time I was around 40 000 miles).

We had always speculated that it was the coil packs and I have followed the thread for a while now.
Please keep us posted on your driving after replacing all 4 coil packs.

I have not replaced my coil packs yet ( I am around 55 000 miles now)..
I have driven trough many miles with the "stutter" and oddly enough it is not getting worse per se nor is it causing a CEL on my Fit. Usually during the winter it is a bit more pronounced and happens more often, but in general i still get great gas mileage and only experience the stutter in city driving, anyway please keep us posted on your experience.
I want to make sure the problem is 100% traced to the bad coil packs before I buy 4 of them (my honda dealer did not approve any work as my warranty is expired) and I will have to pay out of pocket..
Thanks
