Well Ben Its just a bit different I'm afraid and its only the rattle I've got, there's a stack of power, its very smooth and according to my mate Al, who followed me for 50 miles on Saturday puts absolutely nothing out.
Anyway I've got a battle plan in place.
I spoke to the diesel guy I've used for decades this afternoon and he says he can test them for £12 each. However his advice is that in his experience its likely to be just one injector and the only place to get a definitive answer is the Toyota dealer. This is obviously good advice as I don't have to take it to bits first.
Rang Toyota service and the guy was conversant in Cruiser dialect so for £40 its going in tomorrow to have a health check on the injectors and then we'll see.
