hey all...i have a 2000 AUII Fairmont Ghia V8 5ltr and it is flat spotting on full throttle....its even causing my tacho to jump revs when the engine is flat spotting.....not sure wat it is cause i wanna take the car to calder and i gotta get rid of the flat spotting before taking it there.....

i thought it could be the oxygen sensor but ive been told it could be anything.....help would be much appreciated

cheers

Check the Coil Packs. They tend to go at around 100,000km's.
