OK... OK

The Old Me:
"So, the vacuum deal on the front part of the motor may not make enough pressure..."

The New and Improved Me (and by improved I mean having had all impurities of thought and deed scrubbed away by the benevolent derision of those so obviously surperior in their understanding of things mechanical [actually, a fairly broad swath of the general population]):
"The vacuum pump attached to at the 4:00 position on the forward portion of the engine is providing inadequate vacuum for the proper functioning of all dependent systems."
"Houston, we have a problem." (still shuts down slow and rough).
