With the ISCV disconnected is starts up but I have keep some revs otherwise it just cuts out. I guess I need to adjust the idle with the Valve disconnected first to get a base idle.

Should I loosen the TPS and adjust this, I replaced this with PF09 (red 4x4) for the L8.
I left it loose and let the throttle find its natural position, not sure if this is correct.

could it be the fuel pressure reg or CO.?

thanks,
