Not surprised about local auto shops not knowing about Fiero’s and how to work on them. To add insult to injury, I would recommend you check your cooling tubes to make sure they didn’t lift up your car from sides, I don’t know of any shops around here who really knows Fiero’s. You sound competent enough of a do it yourselfer. You can do it, I know you can.
Here’s some advice (if I may offer it)
1) focus on one thing at a time! Otherwise you are going to get overwhelmed and frustrated and then want to quit. One small victory at a time, ok?
(sort out the brakes first - brake fluid behind the booster? Are you sure the brake fluid didn’t come from the m/c? I replaced mine just because it was old, original and had weak pressure. I could feel the difference with the new one.Consider replacing it while you have the brakes down.
2) Double check plugs & wires to make sure all is in order. (firing order that is)
3) Go back and check all manifold bolts to ensure they are tight.
4) Check all your vacuum lines / hoses for leaks.
5) You need to start posting your mechanical/electrical issues in the Technical Discussion section, not here in General, ok?
6) Stay connected to this Forum. It costs you nothing, you get free advice, and most importantly, any problem your Fiero has ever had or is going to have….. someone here has already been there and done that!
