P0441 Fuel Tank Ventilation System - Above Limit

[CJ_Boxster]

Hey Guys, I need some help diagnosing an issue im having with my 97 Boxster.

One day, Im driving 65MPH on the freeway when I hear what sounds like a handgun being fired from inside my engine compartment... The engine didnt hickup or anything but once I was off the freeway the Idle was alittle unstable, moving from 900 - 1100rpm's and I got a CEL with 1 code (P0441 Fuel Tank Ventilation System - Above Limit )

She sometimes stalls during idle and will take about 7 seconds of cranking to start back up & sometimes comes close but doesnt stall.

Also, when I turn off the engine after about 10min drive I'll hear a sound similar to a low toned 1 second honk coming from either the passenger front Fender or engine bay... Hard to tell, really.

Any ideas what would cause all these symptoms?

I would check for oil in coolant.....

Also check compression on each cylinder.

does your temperature gauge rise?

check your water pump to make sure the pulley is still there.

Sorry, No im not having any cooling issues what so ever... This problem is related to vacum and Emissions components. All my cooling system components are there and working.

Figured it out...

I hooked my Boxster up to our shops Durametric software and ran the Drive Links section and activated the Fuel Evap Valve and sure enough I couldnt hear it click on & off like it should once the durametric software tries to activate it. So I gave it afew hard taps with the knob of a screwdriver and sure enough it started clicking on & off and the honking went away... Part number is 996.110.129.05 circled in RED
