Hi,
Will idle at 500 but drop to 400 now and gain, other times will jump between 500 and 400. Doesn't seem to do it at any specific time, uphill+downhill are the same, throttle position makes no difference. When revved out of gear it will got to full revs and back with no issues, only under load. Got a feeling that there may be a problem with the LSD as well as when slowing down at times its as though the rear wants to slow down more than the front, as though the brakes are getting pumped.
Getting a new exhaust and steering idler today so am going to strip the brakes down at the weekend and just make sure nothing is sticking, also another oil and filter change. Fuel filter also. Nearest Tech 2 to me is Hotel 21 so might have to take a trip to Fife
Cheers,
Iain
