My thought would be a vacuum leak.  Every time I had a problem like that, it was a small crack in a vacuum hose.

[junya92toy]

Mine did that, I unhooked the battery to reset the codes, and it stopped

[92runner [OP]]

[junya92toy]

DId you miss the part about me saying I unhooked the battery to reset the codes?

[pholifer]

[junya92toy]

[junya92toy]

No you dont, you just have to use a paper clip, and use the dianostic port. google it

Mine did something like that and it had a leak on the vacum line by the power steering pump.

[Bobby Hunter]

Re-set the tps sensor

[hansi530]

mine did that and i just kept driving it and it went away its a toyota it fixes it self

[92runner [OP]]

Thanks for all your help havent had time to check any thing yet.

If didnt already know, you can use propane to check for the possible vac leaks.  I had the same issue on 4runner and it was the tps.  If you dont find the vac leak, then Id bet its the tps since you said you have no codes popping up

mine is a leaky head gasket... but it did it whether i was on the brake... rollling down the road... =] good luck!
