Ever since I checked my cam follower, cold starts have been long and sometimes refuse to start the first crank. Ive checked the cf, maybe I put it on wrong, even replaced it. Still rough startups throughout the day. I've read old threads trying to pinpoint the issue here. People have changed: lpfp, hpfp, coils, plugs, carbon cleaning, yet the issue persists. What is the ACTUAL culprit here? I don't want to change all of these parts if they won't fix the issue. If somebody has seen the better days of this problem, please put it here on how you have solved it.
