ZE swapped, no issues before I did this:
Got fuel injectors cleaned and tested (came back good)
Deleted EGR
Changed drive shafts
Now when I accelerate it bucks badly and I can see the RPMS shoot up and down wildly whilst doing so. I tried adjusting the TPS, it's not that. It stalls too after I try and take off. There's no air leaks, no vacuum problems. The VAF was fine before and I can't see it being crap now. Nothing is disconnected. I'm using a known good disty.
Idling, it's perfect. No signs of failure, it's only when I try and drive with some load, I can rev the engine's a-- of whilst idling with no issues at all. It's just when I take off I have issues and it seems to be prone to stalling after take off.
I actually put the fuel hoses on the wrong way when I reinstalled everything and tried to start with no effect. I dunno if this could have stuffed anything up. There really was not too much pressure coming out of the fuel lines when I took them off and tried cranking. Also, I do have a new fuel filter.
Not sure if my fuel pump is on it's way out.

Re: Serious bucking and stalling
it might be your fuel pump if it didnt push a good amount out of it.
what ecu are you running?
to me it sound like a vac leak on the manifold.
you also might have a bad tps.

Re: Serious bucking and stalling
Don't see how the TPS could go faulty all of a sudden but do have a spare to play with.
Not much fuel came out of fuel hose when I had the engine cranking and the hose off the injector rails. I might try taking it off again, jumping FP and GND on the diagnostics box and seeing how much pours out. I should get a nice amount of fuel pouring out right?
EDIT:
OK I forgot one grounding wire in the wiring loom... Connected it back to the engine and went around the block about 3 times this morning with no issue whatsoever....
Will check it again tomorrow on a much longer drive to work.

but your tps is something that is very common with these cars to go out.
