[s-cars] Help!

[Jeff Sevel]

Driving home last night, I noticed my 95.5s6 began to idle
strangely...almost a rumble. I was stuck in some stop and go traffic...when
I shifted into 2nd and gave it some gas, there was very little power. No
strange noises...RPM's seemed to be normal, but it felt as if my accleration
was at 50% normal...back down to a roll and the car seemed to vibrate and
shake a bit. After my initial panic, shopped at Chevron for a fresh fill-up
of 92 and went a few miles home to check the vitals, leaks, etc. I was down
about 3/4 qt of oil (due for my oil change in 500 miles). It's been a super
hot summer in Seattle and I have had to do some commuting lately, so I
understand this could have had some affect on oil consumption. I keep my
engine clean, so now new signs of leaks or anything. No warning lights on
the dash. Oil pressure fine. After adding the oil, started her up and the
engine sounded fine...then gave it a little gas, and back to that same
shaky, rumbling idle. No apparent noises or nocking, pinging, etc. But I was
too afraid to drive her around the block.

My trused mechanic will be back onl Monday am, but I am a bit desperate to
get some feedback beforehand. Cub (of the highly recommended Redmond
Werkshop) if you pick this up please give me a call. Otherwise, can anyone
out there help me troubleshoot? I cant sleep until I figure what is causing
this. As always, I have my fingers crossed that it's nothing major.

Thanks for your help.
