My engine (c20let) is running like crap. It wants to stall and die and bogs right down when trying to drive it..
Bit of background...
Refitted the engine before PVS. Alt jammed causing the alt ground lead to melt and burn out. That was replaced as was the insides of the alt. Found after that the car would idle off and do this same as it is now when you try and drive/put it under load.
I swapped ECUs as a last try and it fixed the prob straight away. Like night and day running. The ECU light was ok, but i tookit that was from the copied chips. (gave a 69 code which is air temp sensor in the AFM so not a huge worry)
Drove to pv and back then a few days driving, then to the mot. About 400+ miles and it was total and drove fine. Ecu light was on showing the air temp sensor, so i swapped AFM didn't change, so i took it that it was the chips.
Drove to the mot ok even is stop start traffic, picked it up and it started doing it about a mile down the road.
Got a spare std ecu, fitted and tested it, drove around the block ok, but i thought the idle was off, drove to Dan's and it did it bogged down twice on way. Dieing fully on his drive popping the fuse that powers the light too.. which it did 3 more times soon as i tried to drive it. Fitted a chipped ecu and it stopped popping the fuse. Drove back to mine (1mile ish) and it didn't do it at all.... Then started again and now wont stop.
Small video of the clocks/short drive so you can see what i mean.

I've checked..
Plugs all ok,
Leads all ok,
Dizzy and arm all ok,
Everything is plugged in,
Grounds all connect,
Swapped AFMs still does it,
New CTS,
Tps clicks so i think its ok,
Fuel pump/reply both fine,
Fuel pressure fine.
Wiring looks ok.
3 different ECUs tried. (1 chipped, 2std)
No ECU light on.
I'm at a total lose of what to look at next.....
