probs with 24valve carlton
my mate is having problems with his 3.0 24valve carlton.
Occasionally when driving along, the revs will suddenly drop right down and then pick up again a second later.
It first does it after about half an hours driving, and then happens on a regular basis after this.
An auto electricion has spent hours trying to find the problem, and its had a couple of trips to a main dealership with no success.
I have heard from others in the past that this has happened when the dizzy is on its way out??
(it has has new dizzy cap, rotor arm, leads, crank position sensor (ithink), and the afm has been checked)
Idle air control valve? Clogged air filter? Throttle body clogged up with cr*p? If it's the TB, spray some carb/fuel injection cleaner into it.
