Misfire/Lean codes

[BMD]

I started a thread last week about an idle shake (see here)

Changed the spark plugs (was planning on doing anyway) seemed to help slightly. Changed plug wires (motorcraft) and got worse/new problems. Changed to plug wires again (Napa) and new ignition coil. Not as bad as before but still has issues, at least now I have engine codes. Gives me lean on bank 2, misfire on 6, misfire on 5, random/multiple misfire (cant remember which) and misfire on startup codes. Any thoughts, or maybe something I may have bumped?

check cylinders 5 and 6

Make sure cylinders 5 and 6 are wired to the correct terminals on the coilpack.

Are you losing coolant at all? Have you overheated recently?

Well I feel like an idiot. Funny that it ran better with the crossed wires then the replacement motor craft ones (those I replaced single wire at a time instead of doing all at once). Tomorrow I'll know better about it still running lean or the shake

Cleared all the codes and no new ones. Still has the shake at idle though if anyone has any suggestions on that, or at least what to even check over/look for.

I have a random shake at idle in park I've never been able to figure out. Odd thing is it goes away sitting in drive.

Mine is almost opposite.

Sometimes it will be fine idling in park but then in gear it will shake a little (and still shake when back in park). At this point its almost inconsistent. Definitely better after the plugs/wires/coil. As I've only had it a couple months I think I will try running a few gas tanks with some injector cleaner in it, see if maybe that helps at all.

If yours is Flex Fuel run a tank of E85 then change the fuel filter. Really cleans everything out.

Nice thought but I don't think I have ever seen E85 for sale.

One thing I'm starting to notice, maybe coincidence, but it seems like the warmer it is (over 50) is when it seems to have a more noticeable shake, where as when it is below freezing I don't really notice a shake at all.

Just going by a quick search looks like you have to go to NY or Phily
