2000 VT Calais

[calaisperth]

Hi I am new here I was wondering if anyone knows the fault here...
when I am driving my VT Calais I get this kick back from either the transmission or the diff when I reach about 80kms if I try to accelerate it lack all power and gets worse.
I have taken if to a holden dealer and they say they can't find a fault? it also struggles to go up hills doing the same thing. I have to drive up the hill in 3rd at 60kms where the speed is 80kms.
thanks

Hey mate, Im new to this holden stuff, but i have just fixed the same issue in my 98 VT s-pak with a set of plugs and leads. I know it sound silly, as someone may have already looked at them, mine looked fine too, plugs had good burn and leads tested ok-fair, but i changed them as im going nuts after 3 weeks and there it was, car fine........ I have an engine shop and mainly concentrate on Nostalgic/pre 80's vehicles so all this computer s$%t is new to me. Worth a look mate.
