Ed i spoke to you on the phone about this before.:grinning:
Right the fan hardly comes on in traffic, i sat for an hour in stopstart traffic yesterday and the temp needle didnt budge but the fan cycled a few times,but after a run as your pulling upto park the fan will come on and go off.
I have had it on cold start up the fan started running , which seemed very odd but hasnt done it since.
This problem only really happens when the ambient temp is quite high around the 20deg c and above mark.
Silly question dont think its the clutch slipping at high rpm and road speed?
Have you got something that could talk with this car, so i could take it for a thrash and watch the AFR, engine temp etc?
What will happen on these later cars if i disconnect the main o2 sensor?
