fluctuating idle problem on my 02 tacoma V6

i have a 2002 toyota Tacoma V6 4x4 with 240k miles. In the last few months, it's been having fluctuating idle when i'm stop at light causing truck to move forward/also in parking position. no check engine light, The funny thing is some days, idling are worst then other. I check all vaccuum hoses and discover the small hose connecting to air filter box had crack. I fixed the hose, clean throttle body, could not find any other hoses w/cracks or leak. fluctuating idle problem continues ....any help or suggestion guys. What do i need to check or change.

 

floating idle is most often caused by vaccum leaks, check all gaskets and hoses by spraying ether around them

might also need a new fuel filter
