Omega General Help / Re: Omega V6 - Stalls @ 1k RPM/ Won't Idle

Ok little update to this.
We changed the maf, ordered the correct ICV pipe from germany still no difference to the high idle so we were at a loose end.
Ended up buying "My Naff Code Reader" to see the live data from the sensors and low and behold our isse was shown as soon as it was plugged it, at throttle close the TPS was showing a value of 4.78v with the simulated full load switch = active with the simulated idle switch being inactive.
Unplugged the TPS sensor and the idle went down to 600 RMP, with a little hunting, so plugged in a TPS sensor we had lying around and the voltage read 4 volts but turned it to where it was at near zero, and the idle switch was now active and the idle was a steady 600 with no issues apart from the slight hum/ vibration from the G cams. turned it up to where it would report the 4v and low and behold our high idle was back.
Turns out the rod that connects into the TPS sensor on the TB that was attached to the long plenum is rotated 90 degree's from the stock one on the x25xe that we removed, also the flap open in the opposite direction so when at WOT on the long plenum TB the car is registering 0% throttle, so needing to refit the old x25xe Tb to rectify out issue and the old meega will be back on the road
