Re: Q about variator To marlon from oversea.
Wrinx is right, it doesn't sound like the variator or the magnetic actuator (which is what I actually tinkered with).
Clean out the Air Flow Meter and Throttle Body with carb cleaner. If you haven't done this you will see that it is very oily in there.
Is the car kangarooing under load, or when you are travelling at a constant speed ????
Constant speed could suggest the lambda probe, but kangarooing is normally a sign of a weak mixture I think.
Check the plugs and leads (again as Wrinx said) for proper tight connections/splits etc.
We could do with a bit more info on when the car kangaroos, hot/cold/both, accelerating, constant speed etc.
cheers and welcome BTW
