Fellow Minians, i need your help
i have a 04 MCS 140K on the Dash
im getting the following codes
P0300
RANDOM/MULTIPLE mISFIRE
P2096
POST CATALYST FUEL TRIM sYSTEM TOO LEAN (BANK1)
P0301
CYLINDER 1 MISfIRE
P0313
mISFIRE DETECED LOW FUEL
where would be a good place to start for this issue its starting to get aggrevating

Since you're getting a low fuel code, I'd check the fuel pressure and do a compression test as well. Low fuel pressure could cause your lean condition, as well as misfires. I'd start there to eliminate those and by doing a compression test, you'll be able to check the plugs while you're at it.

Can you post pics of the sparkplugs?
It could be just too cold of a plug, or a byproduct of the misfire, or even bad gaskets on the valve cover...
My gut says you fuel pump might have a low psi and the plugs are dirty as a result of a misfires...
I would see if you can borrow a fuel psi tester and plug it into the rail (under the intercooler there is a valve) and check it out.

Thanks ZippyNH
So i took a second look at the #2 spark plug and the helicoil came out with it.
the #1 SP. is stuck and is currently being removed with the tighten then loosen method. My plan is too first remove sp #1 then try to reinstall a coil in #2 SP hole.
(My question with that is, Because i removed the old helicoil do you think i be able to reinstall one?)
after that ill be doing a fuel psi test to determine if it is a failing fuel pump. fuel filter or if its an electrical problem
then ill do the compression test
