thanks. that's what i did. i was getting the P2004, P2005, P2016, and P2021 CELs. i disabled those CELs and enabled the tgv fixes that included those CELs. but i left the other tgv related fixes and CELs alone, so i haven't enabled all the tgv fixes nor have i disabled all the tgv CELs. should i go ahead and enable/disable those even if those CELs haven't been thrown?
also, should i clear the CELs first with a scan tool before disabling them? or does that not matter?
