Well, its not "all of a sudden" because, yet again, you forgot to state that you changed distributor parts prior to this issue. Thats important and probably your current source of the problem. You did this before multiple times where you choose to ignore related issues that were apparently addressed and you, again, do not provide all the involved history. You still havent even stated (as I previously asked) how the issues were resolved. You mention "people" told you stuff but dont explain at all if these were automotive professionals or just a friends.
Im saving myself added time now by saying what youve forced me to repeatedly say before...
GO TO A MECHANIC because you have proven to be incapable of helping yourself by clearly answering what is asked of you in this forum. You seem to be a nice guy and you havent been rude, but you make it nearly impossible to help you here. Good luck.
