Todd,

In the past when doing an oil change I've left the oil cap off while
turning the engine over to circulate the oil.  I noticed that the
vehicle did not run the same as when the oil cap was in position.  From
this I conclude it would make a difference.

I have heard that a bad valve can cause the electronics to overheat and
burn out.

I was having the van smogged and had the mechainc take a look at it. He
verified that the individual components seem to be in spec.
He did discover that one of the plug wires was intermittantly bad - but
did not have a new set around. So the next step will be to replace the
plug wires and see if that makes a difference.
I'll also be checking all the vacuum hoses.

The mechanic did adjust the AFM mixture and throttle switch - and that
alone made a noticable difference.
Is there a concensus that having a crack or leak in the oil filler tube
will cause problems as well?
