Was a R&D Tech. For what was the big 3, Engineering Departments and its Sub-contractors here in Detroit. stopped working on my own cars in 1995. reason being, I could afford too. Now I don’t work anymore because of a fixed broken neck, that’s inhibiting me to work for only a couple hours a day. Now on disability, which gives me no extra money. I’m once again working on my own vehicle, Olds Bravada 4.2 I6. What I’m trying to say is once I learn this new way to trouble shoot. I should help me out immensely. Here me go, into the 21st. century.
