For the first ten minutes, everything was fine with no issues and then it started happening again.

It's stop-and-go traffic, so I bring up the clutch pedal with minimal revs and pull forward. As I dip the clutch pedal, the revs fly up to 3,000 revs and bounce between that and around 900 constantly. I bring up the clutch pedal again and pull forward and the process starts all over. Here's the interesting part that I learned this time...as I stop, I put the car into neutral and the issue goes away completely. If I leave it in 1st, it revs a couple of times and eventually settles down. As an experiment, I put it in 1st and crept forward after bringing the clutch pedal up again, but this time, I coast slightly downhill (clutch pedal depressed fully) and leave the gear in 1st and the revs continue to swing. While still continuing to coast, I take it out of gear into neutral and the revs calm down and are stable at 950rpm.

So, this only seems to happen in gear...I don't know why, but it sure is strange.

I have some good news with regard to this particular issue. Neal at The Racer's Line cleaned the throttle body and checked the pins on the harness to the MAF. The pins looked a little loose, so he tightened them up and added some hot glue to make sure they were secure. Since then, going on three days now, I have had no issues with the idle. Keeping my fingers crossed...
