My bonne is still doing it as well. It would even sometimes stall out, but in all fairness to the car, I haven't taken any time to look at it. Mine will drop RPM in park, and it use to stall even. Then it started to stutter in driving gears. I pulled the plug wires and reseated them, The problems stopped in the drive gears and it ceased trying to stall on me in park, but it still had a slight stutter, just not enough to stall it out. I think mine is the front plug wire closest to the air box. Hopefully that will prove to be correct when I get the chance to look at it.
