WilliEGooN,
Welcome to the site!
If you've tuned it up to spec's (as you've stated), and this problem just started all at once, I'd start checking ALL your vacuum hoses (as you stated in your first post?). Old hoses can look good and be bad (leak). Check them for small cracking by bending them sharply and check the entire length of each hose (remember, this checking is free!). Over the years I've had good luck locating "most" vacuum leaks using a three foot length of CLEAN/UNUSED fuel hose. I put some cotton in my bad ear, hold one end of the hose up to my good ear and use the other end to go slowly around the carb base gasket, the power brake check valve, egr valve, and then slowly check each vacuum hose. Listen for a hissing sound! While checking the hoses, also check all plastic hose barbs (such as where the hoses mount on the charcoal cannister, etc.)
Remember, this checking will only cost you some time (unless you need to buy the hose and/or cotton...LOL)!
