Is it simply a feature of the indirect injection design of the 1hz for the motor to 'chug' when too much throttle is applied under load?
I stop it simply by backing off the throttle and if I don't need to gear down due to the grade it keeps going but slower. I don't care how slow it goes.
I've never driven an 80 series with any other motor (like a 1hdt or 1hdft turbo diesel) so have no experience to compare against.
Does anything need to be done with the motor to maybe address any underlying problem? I did the shims at 600 k km's and the motor is now over 686 k km's so shims are due at 700 k kms along with the timing belt + tensioner + water pump.
The injector pump was renewed 12 years ago at just over 500 k km's plus injectors were done then too.
