I have having a misfire issue with my 2005 gx and no one has

Customer Question

I have having a misfire issue with my 2005 gx and no one has been able to figure it out.

Hello, my name is***** all has been replaced? Is misfire constant? Thanks.

Did you read the section of 'what I have tried already?" is saysI have having a misfire issue with my 2005 gx and no one has been able to figure it out. It was misfiring in 2&3 and was sputtering during driving at all rpm. Light was on solid. They replaced the plugs (which were 50k miles on 100k warranty). We also replaced cvt fluid by chance. The car drove fine after that.
100 miles later the car more heavily misfired and was undriveable. It would idle OK but when given gas would sputter very hard and die. Maintenance light was only flashing.
The original mechanic looked into it and found cyclinder 1 misfiring only. He inspected and replaced all 4 coils as he found cracks in the top and down the plastic shaft, from where it turns 90 degree. It still misfired, and light stayed intermittently. He did a compression test and found no issues. He adjusted the valves and still misfiring. We sent it to dealer and they did an emission test and found high carbon and suspect it is a blown head gasket. We brought it back and did a leak down test and found no leak.
Any ideas?

Misfire is not constant, it will have power for a few min and then will misfire heavily, then clear up and drive for a bit.

Are you reading the info which was submitted through the site? it doesn't seem like it.
Customer: replied 1 year ago.
can you confirm your experience with Honda Civic GX?
Expert:  Dan replied 1 year ago.

None of the original information you posted showed up. I have only worked on these a few times but when it comes down to it, they are all pretty similar. Does it still idle fine?

Customer: replied 1 year ago.
it idles fine. Here is the original info, can you confirm you have read this? I'm not impressed with all this back and forth. I have worked on hondas 10x you already I am not a honda 'expert' as this website says you are.I have having a misfire issue with my 2005 gx and no one has been able to figure it out.
