its possible you intake air temp is getting too hot... wether the ecu does chuck a wobbly for it being 'too' hot, im not sure.
try driving with the bonnet off  cheapest way to test.

not sure if you have a boost guage, but if not, it could be overboosting... like the hose to the wastegate actuator maybe leaking or fallen off  not sure....

It sounds like the engine is pingning and the knock sensor is pulling timing and boost out.

hmmm...
no we didnt upgrade the fuel pump.. $$$$
but since we put the engine in, i now have to have the car on contact for (5-10secs) it to start properly, so maybe fuel pump.
the hood is a problem, but it wouldnt den explain why it does it sometimes when its cold....
lol
it choses the best time to fuk up, got beaten by a friend in a old old peugeout that i used to beat wit the 5sfe..
cheers

I reckon that 3SGTE is living on borrowed time.
Get a decent fuel pump in the car, get some airflow to the IC and put it on a dyno to see what the A/F ratios are doing.

Agreed - no fule + super heatsoak = prty dead 3sgte soon ..
id suggest not racing it either while in your current state - or else that borrowed timeframe will become even shorter ..

Have you got a thermostat It may be that the engine is not getting to operating temp as you said it does it when it's cold and rainy The ECU will also holds boost to (low) if the engine is below operating temp .

The first one is nothing, forget that.
The second one is a vacuum hose, it looks like it should be connected to a boost gauge or something. Pluggin it up will be fine. Check all the vacuum lines coming off you manifold/TB/turbo/boost sensor and make sure they're all plugged in and not leaking or cracked. If one of those hoses is not plugged inproperly, there's gonna be dramas.
Good luck.

Check the idle up vac lines going to the power steering pump. This is a common failure area.
Whats your idle like with your boostgauge?

with what your discribing i belive that its a ECU problem its not mapped properlly.
btw T peice dussnt realli matter in reality which hose goes hwhere n stuff cause its all the same as long as the hose fits.
ppl are gonna b arguing now about it but ive worked on so many cars and theres no issue about where the t peice sits n where its plugged.
but have the fuel system ecu remapped cause it sounds like its off.... by MILES!

Check it out, but im pretty sure fuel isn't an issue, my gen II 3sgte boosts to 14 psi fine with no fuel issues. Unless your fuel pump is screwed it should do the job.
I really think you just need to make sure you have no air leaks and it'll be fine.

Cycleofabuse >i've heard when swapping a 5sfe with a 3sgte you have to upgrade the fuel pump. but in a st162 (3sge to 3sgte) the fuel pump should be fine. mine wasn't changed and it boosts fine.
Just a suggestion Question: what ignitor did you use in your swap?did u use the one from the 5sfe or a 3sgte one?
check here from more info.

You can get heaps of info off this site too.

update...
umm i changed a couple of the hoses...
moved the boost gauge to where the other t-piece was...
and ye...
according to the boost gauge its boosting properly now...
havn't exactly felt more power, just smoother power on and its idle's way better...
also havnt experience the problem, with it retarding the boost... yet.. hopefully i won't...
heard alot of stuff bout the fuel pump, some ppl say its good for 400hp, but ye...
also found a hole in the hose that goes to the master cylinder, from the intake... need to change...
hopefully all is good now...
thanks every1
