Hi,

Hope everyone had a safe and pleasant Easter.
I'm a bit stumped on this one. 06 987S runs well when cold. Settles into a nice smooth idle. As soon as it comes off choke, it starts to flutter and runs rich, to the point it's eye watering. Has new plugs and coils. New AOS. IPD plenum, new genuine maf and GT3 throttle body. It ran the same as this before all that was done. So made no difference. Unplugging maf makes no difference.
Any ideas or experience appreciated.

Cheers
Scott

How are the fuel trims?

I had a stock tune run through the ecu again. The guy that did it (has a lot of experience tuning Lambo's, McLarens etc) said it was a stock tune. I plugged the ecu back in, and the car fired up straight away. No CEL's. Mind you, it did the nice cold start idle before I had the ecu map checked.
Any easy way to check?

Did you check your oil for fuel? How does it run when cruising at 3000 or so?
If you have fuel contamination, I might think about leaking injectors. If you do have leaking injectors, I wouldn’t run it too long as that’s a cause of the infamous bore score issue if left too long. If you’ve been messing with tune, there sounds to be a setting issue with the tune as something wasn’t put back right.
