H8 mine was porking gas and having some really odd acceleration/idle revving issue.  Noticed some gas smelling fluid coming from the AAP BVSV vacuum line and swapped the line out for a clear tube. Found this...

So I am guessing that my AAP Diaphragm is blown out and fuel is getting sucked into the vacuum system.  Maybe you are having a similar issue?  :think:

Ended up breaking the plastic nipple off the BVSV so I'll need to find a new one of those as well as rebuild the AAP.

OR

I could delete the AAP all together!  The short time I had to do research last night it seems to me the AAP is only there to force more fuel into the accel nozzle when the engine is cold.  Might try it as "cold" ambient down here usually means ~40F for like 10 days of the year. Doesn't take long to warm the engine up...




I pulled the AAP vac line off and no fuel was there but that clear line trick is genius!  I may try to get ahold of some today and see what I can see.
