Gday
My car has started running a bit rough when it's cold, but only last for about 30 seconds. When i take off the car will run normal then start to have a flatspot at around 2000rpm and will surge a bit, then when you put your foot down a little further it will go away. When it does go away the car will not surge anymore but seems to still have a bit of trouble getting past that 2000rpm and seems to go up the rev range a bit slower. Anyone know what this could be? I just replaced the plugs and the leads are new iv checked for vacume leaks aswell. Could the dizzy be stuffing up? Cheers

blocked cat convertor. mine had a flat spot like yours, turned out the cat was blocked and needed to be replaced. got a new one and was all good
oh and as for your rough running on cold starts, that was also happening to me when my auxillary shaft was on its way out.

Ok cheers
The cat is only a year old and its a stainless 2.5" highflow so that should still be alright, might have check that shaft out I think i might take it to ultratune and get them to put it on there diag and see if any of the sensors are dead, hopefully its just a sensor.

get the exhaust sniffed by ultra-tune etc or if you have a timing light me. I would short out the top and bottom pins on the left of the diagnostic plug and check the base ignition timing and idle.

ok i went to ultratune this morning, no sensors were dead. Turns out my fuel filters was 90% blocked and you could barely blow through it. The car feels heaps more torquey and revs up much smoother.
Also my timing on my dizzy has been advanced 6 degrees. I havn't done a complete cold start yet, but the car feels heaps stronger. Hopefully its fine tommorow morning. Cheers

If it was the case of just a blocked filter...then I think i shall go and change mine too and see how I go  ...hopefully mine is just the filter and not the auxiliary as well.
phong =P~

If it is the auxiliary shaft. Say hello to a new engine!
Came to a conclusion that the only way for the aux shaft to seize is throught no oil.

ok drove it this morning and all seems fine no chuggin and no flat spots before 2000rpm and revs up much smoother. How does the auxilary shaft go by the way?
Cheers
