testbook can do it but sometimes wont coms with the ecu i have the original 14cux tester because of this issue.
throttle position swithc is a fave so to is a afm fault as well.
for all the simple bits of 14 cux when it is not happy it still needs a fault read to see and a live data test to see if everything is doing what it should

well to be honest apart from the ecu, the AFM and throttle pot is pretty much the only things left to change. Without the test gear its hard to rule things out and i have already forked out on a stepper motor that was okay anyway. Got a local independent looking at it next week, I'll report the findings!!

That is a possibility although a bit thin. Take stepper off and apply a small amount of RTV and put it back on, that should at least work as a temporary test/fix.

how did you up the idle, base idle re set or just on the cable?

base idle, as per haynes and on here. blocked off the plenum pipe and turned the allen screw till revs about 500 etc. the result was a lovely idle at 750ish when restarted.
but still started with bumpy 300 revs. steps up to 1500 then back down to 750,, however engaging D or R in this idling means back to bumpy 300 revs or sometimes a stall.
Cable is set perfect as far as slack in the linkage goes i.e 1.5mm or so

The so called gasket is only a large fibre washer was it not
quite right, it is a large fibre washer as you rightly pointed out!! :clap2:
but the throttle pot "gasket" is a gasket and is still not there!!:5bcheers2:

well mine was similar on my old 3.9, due to high miles no love (before I had it) a probably stretched timing chain etc. I had changed the tps dizzy amp stepper and afm and they were set properly but in the end with timing and base idle play the best we could get was about 500 ish rpm and it did come close to stalling on a hot day when put in gear sometimes, especailly with the steering on full lock. although it did always start with a rev rise and more so when cold.

yes how did you guess , dont trust any so called landrover mechanics ever- waste of money, better off doing it yourself or even just getting jo blogs garage to do simple mechanical work.
do all my own work on the landy now bar mot tests, its always given the time and attention it needs for a 40 year old motor and no bull**** "thats how it should be" or being charged for half a job!
dummy spat, lol

could be your lambdas plying up. I never had to worry about that on mine as it was catless. worth getting the fault code reader
