I searched and couldn't find much.

Description of Symptoms:

When cruising in any gear at low RPMs (>3500), when i punch the gas, the car shakes/hesitates/studders almost like it did when one of my plug wires popped off not too long ago. I recently seafoamed and replaced the plugs with Autolights from walmart.

Notes:
This behavior isn't as severe when starting from a dead stop and ripping through the gears, i can still feel a little bit of studder, but its hard to notice.
When sitting and idleing, the RPM's will begin to oscillate between normal idle and about 400 RPM's
The car has been sitting for almost a month with about 1/8 tank of gas and i just filled up with 87.

Possible Prognosis:
Condensation/water in the gas. Faulty plugs.

Any other guesses or suggestions?

 

switch the plugs out for some regular ngk's and throw in some fuel injector cleaner with your next fillup, and go from there.....
