Held the gas down while starting and it rev'd super high - won't hold though - but tons of exhaust out the tailpipes. Probably un burnt fuel.

If I give the passenger side Throttle Sensor a little tap - I can hear a rattle - when I do the same on the driver's side - no rattle - hymmm.

My passenger side throttle makes a springy sound if I tap it, the driver side doesnt.

Sounds pretty similar to what my car was doing. Assuming it will let you: try what I did... clear the codes out, start the engine with the gas pedal down (dont go up to 7500 or anything, just whatever is required to get it to run), then lower it down very slowly to idle speed... and if it will hold idle let it idle for a minute, then shut it off and wait, turn it back on.

No idea what was going on, or why that fixed it... but thats what I did and then it never acted up or gave me throttle codes again.

ok - some good news --- I tried to erase codes via code reader. And Start it up right away - missed it for the first 3 trys but then got it on the 4th try - it rev'd high for a bit and as soon as I let off the gas rpms would drop to 500 or so then to 1000 - i held it at 1100 rpm to hold a steady idle and the ecu then learned the steady idle.

But still in Limp mode as it won't let me rev higher than 1500 rpm. And the codes come back with Dash lights. Check engine soon and Traction control light ugg.
