I have a 1jzgte non vvti which is staying in limp mode. I did the flash codes and got code 21 (O2 sensor) and code 41 and 47 ( throttle position sensor) I have put 2 different TPS sensors in and made no difference both are known to be good. It's running a single turbo with a piggyback ecu. I took the 1jz ecu apart and replaced a capacitor which seemed to be leaking everything else seemed ok. Power going to piggyback ecu also. Checked grounds, vacuum lines etc. A friends 1jz will run without the tps and not go into limp mode. doesnt seem to make a difference to rnning if the tps is plugged n or not. getting the neccessary voltage and the grounds are fine at the plugs.

Anyone any ideas what to check next?

Below is a video of what it's doing. Car idles fine and it cuts at about 2300rpm. Video is of throttle been held down. No problem starting etc. Any suggestions/ help is greatly appreciated. Thanks
