v70 idle low
 

hey guys, I just got my 2006 Volvo v70 running. but when I start it up, it idles at 1000rpm for about 30 secs and then drops down to as low as 1000-400. when at low idle it starts to chug and then die. but I get the exact same result every time I start it up.
I am not sure what could cause this but any help would be appreciated
thanks!

Could be a few things - 1) low fuel pressure 2) issues with the throttle body (read up on Volvo ETM issues) 3) intake air leaks - cracked intake boot/torn hoses etc.
