I don't know if base idle adjustment is ever warranted on these trucks. A PO of my latest LWB dicked with it, and it occasionally hot-starts with 1500 rpm idle.
Ive had to adjust base idle when changing displacement, but that shouldnt be a surprise
Not sure, but I have a spare new Lucas rotor in my parts bin.
The only other thing I can think of is maybe your speed transducer (VSS) is not working properly. WSM does not show a way of testing it though.
I found a good deal on a Lucas ignition amplifier
I have had 3 of these fail due to earth ground fault through the rotor.
May I ask where as would like having a spare one of these.
Thanks!
what did you do to resolve this?
Thanks!
Atlantic British was selling them for $37 through their ebay store. Same part number as the one on their website which was nearly double the price. Maybe I should get another.
