well you got me thinkin so i trailered the beast down to my local mechanical wizard ,tolod him what was goin on,gave him a few suggestions as to why the bloody thing would not go as it should and then took a weeks holiday. got back and he reckons th motoor is outa a patrol with the injection outa a late model r30.only thing he could find wrong was 2 of the 3 wires going to the tps were ass about.all els was good the mod was about all u could do to make it work. so now the misses is happy again its out of the shed. thanks guys!
