2003KJ

Ok, So I had been running errands earlier today and lef the KJ outside with the windows down, as it was very nice today (60º). Anywho, I went to turn it around and back it into the garage for the night (the engine is now cold, as it's been sitting outside most of the day). I backed it out of my driveway and went to put it in drive, and the minute I hit drive (i was completely stopped), the KJ began shaking violently like it was attempting to stall, or as if half the cylinders just quit working temporarily. Engine RPM's dropped from the cold running 800 or so it usually is to about 400 (lower than fully warmed RPM's) and then went right back up to 800 again like nothing was wrong. Puzzled I sat there in the middle of the road shifting it b/w drive and reverse several times and it shifted just fine.
What the hell happened???????
There was no smoke, and it only ran rough for about 3 seconds, but man did it shake bad. Exactly as if some cylinders just shut off. I did fill up this morning, but then drove around town.
Wanted to add for those who are new or don't remember, I just had my PCM reprogrammed as part of a TSB on shift related stumble a few weeks ago. But that was a complete and abrupt stall out. No "shaking" period like tonight.
