First, turn off the HTML/MIME stuff.

The last time you posted about this same problem, you mentioned a torn hose
at the back of the engine.  Have you replaced the hose, and have you gone
through the other related hoses to see if you have an air leak elsewhere?
Six year old hoses can get brittle, fourteen year old ones are worse (ask me
how I know!).
