well bad news, been for a 20min drive n spark plug 4 is fine so unless anyone knows of any other cause then im guessing valve or piston ring is at fault.
I noticed on spark plug 3 that the thread was a little wet on the bottom 1 maybe 2 threads but the tip is just dry soot.
ill get a compression test done when I find a tester
oh and don't know if its just because of the bad cylinder but sometimes when on idle the car struggles like mad with the revs dropping right down, I have to rev it to keep it going. other times it just sits at the correct idle speed but obviously still with the misfire.
it drives fine other than the misfire n obvious lack of power
