Check your injector loom...

supercharged how do i do this please

[Supercharged 2]

If you unplug it and measure resistance that will tell you if you have a short or completly dead injector (values are in the Bently manual)

 

But - mine checked out ok and the loom is completly shot, burnt, cracked and falling apart and I suspect it's shorting out intermittently...

 

You really need to get it out the car and have a look, it's held on by 2 allen head bolts but the are awkward to get to as it's above the rail and below the inlet...

Hi Mate,

 

Glad its starting properly now mate :-) so whats the deal now? Can you confirm that from cold it starts fine every time and runs for approx 10 mins before the idle goes tit's up. Also have you checked all your vac hoses double check the 1m from the TB to the ECU, although it sounds temp related so probably your best bet would be to buy (or blag for a test) a blue temp sender from a working G60.

 

Hope this helps

 

Dan
