check for vacuum leaks, and scan the computer for codes. a idle air control valve might be the problem, but it should throw a code. also, a throttle position sensor, but there again, it should throw a code.

thanks, that's what puzzles me though, no codes

That is an odd one, on top of checking for vac leaks, wouldn't hurt to clean the throttle body.
