personal preference really mine had had idling isseus sinds the day i got her then opted out to just delete everything on the intake just have brake vacuum and map vacuum / then used metal putty to fill up the holes in the tb and deleted the water passage going to it



o almost forgotten have 1 more boost pipe connected to operate my acis

I changed the icv valve and idling issue with lights/heaters is fixed



also checked timing with them bridged and it was abng on where it should be with idle at around 800 rpm




thanks for all your help guys



most people go to garages and just time up with out bridging the pins, that was my fear but looks like it has been done properly in the past

Revs shouldn't be too critical as the ecu locks the timing when in diagnostic mode. If you rev it the timing should in theory stay the same.
