If I rev the thing up to around 3000RPM or so and let off the throttle, she just stalls out.

Timing is 15deg on the dot, running at 43psi, vacuum lined regulator increases the fuel pressure as the RPM goes up (hits about 50psi)

Doesn't seem to be any vacuum leaks, and it idles fine.

Everything seems to be normal to me, but I can't stop this thing from stalling out!

Any help is greatly appreciated, thanks guys!

blowoff valve? if its vented then sometimes when you jump right off the throttle it can have the tendency to stall out.

haaving similar issue with 2 sr cars aswell. But both are idle proper, then lean out and stumble on thier face. But under driving afr are good and no problems, just lean stumble at idle.

No aftermarket blowoff or anything, just all completely stock components.

It sounds exactly like it's leaning out, but the fuel pressure remains steady/increasing under acceleration.

Is 43psi too much pressure maybe??? Everywhere I checked said that stock pressure was around there, but maybe they were full of shit!

keep the opinions coming guys haha, thanks again!

specs are :stock fuel line pressure at idle is 36psi ,41 off idle ,
adjust your pressure, your running too rich ......
change your plugs.........
