Jim here too. I have a 1998 Camry, 6 cyl, 3.0, XLE with the same problem. Started on Thursday and I can't drive it unless I do sort of what Jim suggested- apply some gas while either riding the brake or putting the car in neutral.
I've got the book on the car- Here's a couple of hints that you might need. If your 6 cyl burns oil, there is an unwritten or not very well advertised Toyota recall - Engine sludge problem. I just got a new engine 15 months ago and my catalytic converter and Oxygen sensors were not replaced- thus a problem.
Right now, I took the idle up by turning the allen screw next to the throttle body- I'm trying to order the TPS- Throttle Position Sensor- Auto Zone 4 day order and pay in advance. Another parts store 2-3 days. I'll head out on Tues in search for this. According to the book, you need to measure voltage on pin #1 on the TPS connector- with tab at top, the number 1 pin is on the left. Turn on key ignition but do not start. Use a volt meter and measure #1 power to ground. If 5 volts +/- 1volt- then measure pins #2 and #3 when plugged in. This is tougher than it sounds- if less than 5 volts- probably the TPS. That's where I am now. I actually have the part on my counter now- trying to find a replacement. About $50 from some places and can go to nearly $100. If this is the problem, the repair should be relatively simple- two phillips screws holding it on and a connector. If it is the MAF Mass Airflow sensor or IAC Idle Air Control- that will be a topic for later in the week.
Oh yeah, the OBD II code that I just got was a P0120- which states TPS sensor, and can be the other two items above also (MAF and IAC).
You'd think Toyota would know when engines and transmission are having problems and would give you less grief- but these little sensors are problems with a capital "P",
Good luck and hope I helped out some. I have a Chiltons repair manual that I picked up at the local public library- Might want to try that. Wish you and me luck.
