Hey guys,

I have a ba xr6t and recently it has started to muck up, sometimes it takes a few seconds for it to start up when you turn the key and after it has warmed up and sitting in neutral the revs will fluctuate. sometimes drop right down to about 200 then come back up and occasionally it will stall. its fine when im in gear then as soon as you put the clutch in it starts mucking up, is also fine when the engine is still cold.

my tuner reckons either throttle body or computer but im not real keen on spending that much money if its not gonna work.

any help would be graetly appreciated.

cheers, brendan

Check the little plastic valve in the hose that comes out of the rocker cover, they disentegrate and give these symptoms, same happen to me in an auto.

Same issue as I have 05 xr6 turbo manual.

Let me know what you find, I can pull up in a drive through and idle for a bit then it will just stall

Mate get your self some carby cleaner. Has to be. Remove the throttle body. Spray it thoroughly to get all carbon off it. Pay particular attention to Isc valve. Disconnect battery before you start all this. This will also reset base idle and you should be good to go. 9 out of 10 falcon 6 s I've done with your symptoms were that
