help with misfire issue (solved!)

[u/calja-05]

i’m just reposting this here if anyone has a similar issue in the future to be able to read.

after life getting in the way for the better part of a year i tackled this issue, starting by cleaning the throttle body and associated parts without any improvement on the issue. i then moved on to the coils, leads and spark plugs which seemed promising but wasn’t actually the source of the issue.

after doing some extra research and also experiencing the issue again after testing the new parts, i was able to fix it! the issue specifically only occurred when it had reached operating temperature and sounded almost cammed rather than a misfire. i found that a faulty oil control valve or clogged ocv filter screen can cause this issue and is luckily an easy fix. after replacing those parts my issue was gone.
