hey, news to my last thread about my ignition problems, got them sorted.
had the firing order out by one and ia had piston 3 firing where piston 2 was,

was rubbish for a bit.

anyway, i opened up a new kettle of fish.
my car has an intermittent fault with the starter.

sometimes it will fire up no problem, others, i can hear the relay closing, i can hear the starter motor trying, but no cranking.

also, my s12 runs really rough on idle, and i have found it quite hard to get a decent idle speed out of it.

it will take a long while for the revs to settle to idle speed, say 850rpm,

it willl start up from cold at around 1400rpm,will drop to 800-1000rpm,then as the temp guage reads half temp, the idle pics up to around 1250rpm.

could it be the lambda sensor or the air flow sensor or something?
help needed as train to work is poo
