I threw in the towel. Waved the white flag. Hasta la vista babe. It'll have to wait for some other ocasion. And it's all because I have other jobs to start on.
I retro-ed my Buick to the 1979 old school version. Disconnected the ECM/EST and went with a vacuum controled HEI distributor and turbo style Q-jet. I also customized and modded two HEI vacuum distributors with new MSD springs weights and adjustable canister.
All this and could'nt get it right. It was a wierd timing issue. Heck I even got 5-lbs boost, (I have'nt seen it ever get to boost at all).
She would keep a steady idle and do several laps on the highway but when deceleration came she would lose all vacuum and die. I spent the better half of these last four weeks trying to figure it out but could'nt.
I suspected the carb but I swapped it out to the electronic one and it did the same thing. I then thought it may be the distributor so I swapped it out too and no change.
Frustrated I went back to the ECM/EST system. Runs like she used too. No vacuum loss or dying. I'm stumped.
Is there anyone out there that can provide me with a pic of their distributor indicating were you have plug #1 in the firing order? ('78's-80' only).
Because of my brackets I can only drop in the distributor a certain way and I had to relocate #1. This really shoud'nt be a problem. It's a smooth idle, quick start-up and no back-firing so I know It's not the firing order. I must of removed it and dropped it in at least 10-12 times and no matter what it still did the same thing. I've timed it from 8-15 BTDC. No differance.
Oh well, this experiment is inconclusive. That sucks!!!
