I've recently done quite a bit of work on my 87t addressing several oil leaks and trying to suss out my idle problem. I think I've covered all the basics like vaccum hoses and the idle control valve. Anyway I installed new NGK plugs and attempted to set the timing. I could see the degree marks but I couldn't read the numbers. I set it at what I thought was 0 and decided to drive it to see how it did. If it wasn't right I'd just advance it a degree or two. If that didn't do it I'd retard it. Anyway you get the picture. But what I was wondering was is there a way to tell which direction to adjust based on the symtoms of the engine as you drive? For example if it stalls a lot or if you here pinging or knocking from the lifters, that kind of thing. I want my car running right before I make APC adjustments and drive her in the way she was meant to be driven
