starts and dies

[dirtycj5]

aloha!!!!
i have a 99 4runner that just started to act up. it starts and stumbles then dies. if i give it some gas it will run. it seams like the idle is too low. i got it to run for a few min. and the tach was right around 550rpm- 600rpm the manuel says 650- 750rpm how do i adjust to make it higher.
could it be the fuel pum is going bad???
thanks

I would start with new plugs and wires do the full tune up fuel filter included. If you think its a bad fuel pump i dont think it would start and stop it would be dead completely. It could just have low pressure i guess too.

the plugs wires and fuel filter is about 3 months old. i gotta check the pump pressure. from what ive been reading i really think its the IAC because it will run if i hold the gas alittle its just at idle the i have the problem
thanks
