got a question, i have a 2003 gtp that i need some help with. got a po440 code and its for the evap system, it said large vacuum leak. i dont have a scanner or a smoke machine to do a smoke test or to open the purge canster. anyone have any ideas on how to get around that to run some other test? and just for giggles i did replace the gas cap to make sure that wasnt it. thank you all for your time, and any help would be great, i have been going nuts trying to figure something out.
