Thinking about it maybe the cat on my stock downpipe failed from driving before I got the plugs replaced :hmm:. I’ll probably knock the cat out of the Prl pipe and swap it before going to a shop again

Any news?
Honda themselves had placed incorrect plugs after finding incorrect plugs in the first place. Lmao they claimed the box must have been mislabeled. So yet again another free replacement of spark plugs and now the car is running great

Hmmm? Same questions any mods? Have you replaced them before? Running lean or rich?

Lol no. More along the lines of having a misfire and the shop not being able to figure out what's wrong with it. Trying multiple things which led me to dropping the car off multiple times. Mods were ktuner with prl SRI but now stock.

So to make sure I understood correctly this misfiring issue was due to Honda putting in the wrong spark plugs on the car from factory?
No I had a shop replace my plugs, they put in an incorrect gap. Honda found the problem and also put a set that was incorrectly gapped lol

Hmm well they should have checked the plugs already if you took it in for misfire issues, if your problem sounds exactly like mine then maybe have them double check that they still have the correct gap

Mine turned out to be the fuel injectors going out... at 60k miles...
Damn, mind if you give some details about your driving habits, where you pump gas, etc. I’m not sure how long injectors should last on our spec of motor but that sounds early
