Miss fire when engine warm
I have a 90 accord. last week i put a timing belt, head and distributor in it. worked fine after that. yesterday, i noticed it missed alittle while driving. today. started fine, ran fine. as soon as it got warm it was missing bad. didnt want to stay idling. shut it off and it didnt start. came back a couple hours later. started fine. then miss fired when warm. could it be the main relay?
