Need to know what this part is
I need to know what this part is ? It's in the back of my
2005 grand marquie behind the rear tire
Probably part of the EVAP system.
Can I drive without it or no F_O_R
No. Put it back where it belongs. If you cannot do it then wire it up temporarily so you can get to a shop.
Ok thank you
Yes it is part of the evap system and no you can't (shouldn't) drive with it off.
