[leebus]

hi all!
beast wouldnt start due to flooded
i changed the plugs this afternoon and changed both lambda sensors, it then fired up and as been fine since but please tell me if im wrong but it seems a bit rich, it has de cat pipes
the old plugs where slightly black and wet with fuel
looking at the history it had the injectors cleaned and new austec chip a few month ago

I found that these cars are easy to flood, and if you dont catch it on the 1st or 2nd go then get a coffee. I was running decats and the car did run rich. Steve made an adjustment to the ECU and it was fine after that.

Its due to the back pressure difference.
