Been fiddling on and off all weekend, and big thanks to scott for checking a few things with us and being at the end of a phone as a techincal helpline... But think we now have the warm running sorted, having gone for a very long and enjoyable drive this afternoon.
Tried just about every sensor going, with last being the MAP sensor which markedly helped. But the biggest contributer was the inlest manifold had one pipe that was just capped off with a bit of insulation tape that had oppened up therefore sucking in air, and another nipple at the back of the inlet that wasn't even capped off at all, Again sucking in air. Shocking attention to detail TBH, and still need allot of tidying up under there but good enough for now.
So car was basically sucking in a allot of air on cranking causing it to run super rich, then on idle when warm it was sucking in air causing AFR to run rich at idle, and also between a dodgy map on overrun and running rich on cruise was causing the plugs to fowl up, which then took a fair while if at all to clear.....
Can't believe i didn't check the basics first, but heyho. Will see how cold start goes, but hopefully it will atleast be better, but not expecting super things from the GEMS. And Scott has kindly offered to check AFR on idle and across the range again now things seem to be more in order.
PPG growing on me now as well. Love the ratio's and think a 6 speed would be really hard work at this power level. So need to think carefully, if the PPG stays the clutch has got to go.
