Question Small auto problem- lend your ear

Weird annoying issue I'm having.

When ever i drive more than a few miles, then get to my destination, stop and put the car in park. The RPM's suddenly dip for a few seconds, and the car feels like its about to stall, then the RPM's suddenly jump back up to normal.

This doesn't happen when i'm idling normally, at stop lights or anything. It's only when i put the car in park after driving a while.

I have a brand new battery, plugs, wires and O2 sensor.
Also I removed my piggyback a couple of weeks ago and the car has been running fantastic (much better than when it was installed) and then this small issue just appeared a few of days ago.

Not a massive problem, just a pain. Any theories?

^ Nah, I don't think so, kungfugirl. I have this problem too, even before I got my bored TB. I think it just becomes more obvious after the mod. Anyway, I've seen this ever since I got my car back in '03. Maybe, its normal?

i'm pretty sure its not normal, it only just started happening recently. I may get one of those stupid ebay grounding kits and see if that helps, someone mentioned i may have a bad ground
