Code for cylinder 7 misfire, jerk in shift from 1st to 2nd?

Hello so yesterday I did a hard acceleration onto the highway and I got a bad misfire from it. Check engine light came on and it was code for cylinder 7 misfire. I haven't noticed the misfire anymore after not driving it for a day but the jerk in shifting from 1st to 2nd has become more apparent. Just wondering if anyone had had experience with this and knows if it is most likely a bad mass air flow sensor, o2 sensor, spark plugs, or leaky injector etc. thanks a lot.

First post so welcome aboard
Have you just purchased the 43? Regarding the clunk in the transmission, have you an idea when the ATF oil was last flushed and filter changed? This could be you first port of call. Check also if you have any codes registered in the ECU. That could point you to the problem.

I'm sure we would love to hear and see more on your 43 (photos + details)

Thanks for the reply. Yes I just got my c43 less than a month ago. I'm going to ask the previous owner if he ever changed the atf fluid. Thanks for the info as I'm still learning about the c43 haha.

Welcome!!!

Where are you located?


I had the jerk you are talking about but it went away :/

Could have been related to a missfire that went away. Hope you get it resolved

Hello ahh so it seems like many people have had the jerking problem. I'm having my mechanic take it look at it asap and I'll update on what happens.

Btw I'm in upstate NY haven't seen another c43 around here ever
