Hey all,

New to this forum, though y'all may be able to help me..

Recently purchased a vs , and its got a miss when revving it. have replaced coil packs,crank angle sensor, plugs, leads, fuel pump etc, doesn't miss at idle, or if you rev it slowly,

So today, thought I'd try a different air flow meter,, didn't change, but then i unplugged air flow and it was running heaps better, but still a slight miss..

its got me stumped.. Any info or ideas greatly appreciated.

Chris

what he said

[TAS-VK]

Injectors? Have car running and un plug one at a time and if you pull one off and it doesn't change the idle then it's that injector not firing, obviously if you pull one off and it runs a bit worse it's not those ones

Firing order goes from passenger side to drivers side with 1 obviously on the 1st cylinder near air box

have u changed ur fuel filter. going back many moons ago my vs started doing that changed heaps of stuff to find the problem, changed the filter and it stopped it for a few days and then it happened again, put a new filter on and fixed it for a few more days i was using ryco ones then put a valvoline item on and fixed it. my guess was i got a crap lot of fuel
