every once in a while i used to have this prob in my xr8, i mentioned it to the service centre and the clened my throttle body and injectors, this has helped hugely although it did do it again the other day.

get some throttle body cleaner and take off the air intake pipe, spray it down the throat of the throttle body and wipe with a rag

Now and then i have had it happen when switching between different power modes with the adaptive shift auto. Also i had it happen a few times when i was a bit broke and was just using normal unleaded (could be the fuel ?), nowerdays i just run it on premium unleaded and i don't have a problem , unless sometimes still as mentioned above when changing power modes (when 1'st started in the new mode only) .

i have the same problem AU's are prone to fuel pumps so id say it is probbably that i thought it was the altinater not charging the battery but had it tested im sure its my fuel pump

You shouldn't need to use the accelerator to start the car - although I guess you already knew that lol.

Ok, so it's got no problems turning over, just firing yeah? If that's the case what I would look at first would be T/B first, then injectors then work your way from there, filter, pump etc.

i think mine has the same problem

on occasion (on any sort of ground level.. sloping doesnt matter)
ill hit the key and it will kick over then splutter and stall
then ill cranker her over and it wont fire at all..

then i turn it all the way off.. then click slowly thru the ignition(so it gives time for tha fuel pump 2 make sure its all pressurised etc) and ill do it and it will usually start then..
but other occasions it takes ANOTHER kick to start and i have to catch it with some throttle..

very strange

i think ill give the t/b clean a go

Blackers - yours sound like one of 2 things:
1. Idle Speed Control valve not working
2. Battery on its way out.

My olds' car was doing this - starting, idling, then dying. Turned out to be the battery. So clean the ISC out first, and if that doesn't improve it, get the battery tested - it may still show 12 volts, but it may not have much currect capcity so will drain very easily and quickly.

hey i had this prob in my g/f's ef futura i6, would start then stop and shake, and sometimes it would almost start and just shake around like it wasn't firing, got the batt tested it turns out a few plates had collapsed, changed batt, 600cca later it starts like its on speed and hasn't missed a beat, yet. hope it helps

Dont spray right on it.The throttle body cleaner is highly corrosive to plastic and can run straight to the map sensor and stuff it.It has to be removed.
