[QUOTE="hotcobra03, post: 16794012, member: 53096"] I would revisit the lower intake hose again ,and pcv hose and elbows ,, It's the only area to throw both banks lean , Google 03 cobra vacuum hoses documented. Pdf2 has full vacuum harness detailed. Routing of hoses maybe, Clogged or restricted hose. Vacuum harness is small and can be pulled completely to test in hand. Except under intake hose I'm not big on smoke test for this application, Here is pin point test for 02 codes from manual just read all of them and foot notes . There are test to do to see if pcm is actually working which it most likely is .. [URL unfurl="true"]https://www.dropbox.com/s/b9mt30eesukwn5z/02%20pintest.PDF?dl=0[/URL] [/QUOTE]
