I know this probably has no relevance but let me just say I'm the exact same way with working on my car. Something SO simple turns into a day long project. I also swear on my life that "This is the LAST time I work on this garbage!" I also get very frustrated when stuff does not work. I actually have a problem with that. I start to smash EVERYTHING without even consiencely trying to. Its not good. Expensive tools get destroyed, parts get *****'d, AND I look like a maniac madman doing it. All i wanna say is, I know how bad you probably wanna smash something when you cant do something, but just drop it and walk away. Its the best thing you can do. Go eat, take a nap, drink a beer, talk to someone, Smoke a butt whatever you need to calm down, that is, IF you get as stressed out as me.
I just got done working on a 2.8L '84 blazer. It had a nasty vaccuum leak. I THOUGHT I went thorugh the ENTIRE vacuum system. I was ranting and raving "I CHECKED ALL THE VACUUM LINES!!!" But low and behold after I calmed down and looked, the vaccuum advance line that goes to the distibutor was just sitting on the tranny bellhousing.
Needless to say it took all weekend. And I only broke the droplight Once this time!!!
Good luck, and it can't hurt to double even triple check all vaccuum lines, dont just check for connections, check for split lines or cracks that could have been from pulling them off. Hope this helps!
