Stumble issue frequently when I first press the pedal

[Tbolt]

Having a weird issue where if I give my m20 gas, often it will stumble before it revs, sometimes it will nearly stall out. Any ideas? where can I start to hunt this issue down?

Also, it seems to be more stumbly if i just tap the gas real quick and light

I am thinking because I have a tear in my evap solenoid that it may be the cause

i had this problem, went away when i replaced my torn intake boot.

I have this exact same issue, when I really lightly blip the accel.
I posted it a while ago I'll see if I can find the thread, there were some good responses I believe. I havn't fixed it, i'll be seeing my mechanic on Wednesday so i'll see what he says.

The most likely cause of this is intake leaks.

I have a similar problem and i have always heard intake leaks were the culprit. I want to run a smoke test but I don't really have any equipment for that, and haven't found a good cheat for it either. I've been thinking about just using plain air instead of smoke and using a piece of hose as a stethoscope.
