Went out this morning to have a look. Found the problem within five minutes. This is where the TPS use to be connected to. I did have it tucked aware, but it has came loose and got caught in something. As TPS are expensive and hard to come by, I decided to make use of what I had. So out came the Triumph TPS. I started by bringing up the wiring diagrams for the Starlet TPS. I had a search for the Triumph wiring diagrams too, and about 30mins later I had this. Yes it's not tidy, but it works. Next up, reset the trouble codes, let it warm up and took it for a spin. Bridged the ports again, no error codes at all = win On another note, seems to run better too.
