Rough Idle
Hi everybody,
I recently bought a 2000 Boxster S with 68.000 km, now I'm 74.000. I soon, through the nearby garage. had a comprehensive service with new water pump, 83 C° thermostat, new fluids,.. . The car runs very smooth, I'm very satisfied. The only problem occurs after long traffic jams when heat bilds up under the engine compartment. The water temp. is very steady with the marker just after the 0 of the 80 figure. It happens that the idle start fluctuating and I need keeping revs high to prevent stall. If in altitude (2500 m) it's even worst and starting again is difficult. Everything comes back to normal when heat dissipates. It seems there is a sensor fouling when hot.
Has someone experienced something similar, any ideas on root causes.
Additionally, the convertible top operates well. Is there any specific maintenance or lubrication to keep it in perfect shape.
Thanks
Mike Delta
