my ea82t is stalling,when i turn her on she idle's for about 30 seconds and then die's after that as soon as i start her again she then die's straight away if i dont keep the rev's up, i have just put a tdo4 and a full wrx stainless 3 inch pipe and new heads on her but it started to do this before i did the new up grades on her i will take soon photo's tommorow and put on her she looks dam fine even if i do say so myself but this stalling prob has got me stumped??? any help will be greatly appreciated.

I'm fighting the SAME problem with my 88GL10T wagon... Still haven't found the problem at all, things I've checked are cam and distributor timing, vac leaks, spark plugs seated properly, distributor in properly (not 180 deg out) intake manifold bolted down properly, AAV functioning correctly... Still no joy at all, I can get it to idle if I remove the inlet piece from the turbo to the throttle body but then it idles at 2k rpm!

Not sure if any of that will help you at all but it's some things to consider

Any lose / cracked PCV hoses? The oil cap is on, right? It sounds like a massive vacuum leak (which a vent in the PCV system would cause)
