Bad IACV?

[xGUNKX]

So, i got a s13 redtop and it just recently started stalling at idle occasionally.

I went to adjust valve (screw in middle of intake mani runners), and i stripped the screw but still got to turn. Would not come out after 10-15min of turning. Cleaned TB and it seemed to idle better, but still dies out sometimes.

Wondering if this would be bad IACV, FPR, or maybe even fuel pump.
I have Walbro 255 pump as well.
Start watching at 2:30 for when it stalls out

Theres alot of debate on this, so I'll say it as it pertained to me as some swear by it others dont seem to care. Look at your fpr and the vacuum lineattached to it. It it T'd off to anything else? If so that could be "part" of the problem with idle but more so with ur throttle response. I'm not saying this will fix ur idle proble at all, it might not affect it in the slightest. But when I deedicated a single vacuum line to my fpr, my throttle tip-in/response it alot better eswpecially when she is running like shit and about to die.

It stopped stalling out by itself like it just had to be broken in to cleaned TB and IACV.
