Default still surging

I have a new fuel filter, fuel pressure regulator, tps, iac, cleaned the maf, and still have a surge the only mod I know of is a bigger throttle body

I did check vac lines and theres no leaks so I'm completely lost

the only thing I can think of is getting it tuned so it will idle and maybe get more power out of it

Just curious on how you checked your vacuum lines, by sight or with smoke. There's a sticky over on Corral on making your own DIY smoke machine for checking vacuum lines. I remember reading somewhere that 80% of the idle surge threads are vacuum line related.

Maybe it was 79%.
