Hi Again Guys,
Now i have solved the transfer viscous coupling i am back to trying to sort the intermittent running issues.
I took the RR to work again yesterday morning, i had done about 3 - 4 miles when i got stuck in a little jam, the revs dropped to about 100 150 rpm but the car still revved cleanly and pulled without any problems. It done this for a short while whilst moving in a slow jam maybe 3 minutes until the jam cleared and i got going again. A minute or so later i got stuck in a small jam again and was ready for it to drop again but it did not and ran fine for the rest of the trip. The RR is a 3.9 EFi on a 93 plate. If the car had a standard carb with a choke i would suspect the problem to be with the choke either cutting of to soon or to late but with it all being electric i am stuck.
I have so far changed, plugs, coil, ignition amp, coil, rotor arm and cap.
I think i am going to change the coolant temp sensor in case this is misreading the engine temp and is the ecu is confused and is over fueling for a cold engine, the lamda sensor will then detect to much fuel in the exhaust gas maybe and cut the fuel hence the revs dropping.
Any Ideas?.
