codes are as follows p0300,p0301,p0302,p0304 p0305. 29900. miles. plugs are bosch platinum plus 4417 replaced 300 miles ago at onset of problem. new issues have arisen,after 5500 rpm engine code comes on car runs terrible until cools off.but dose not over heat. just changed oil also mobil 1 0w40 euro car formula. i can improve way car drives/runs by disconnecting batt. for 20 seconds .then start car up and runs much better no engine lights, codes until i put tiptronic in man mode and take car to 5000/5500 rpm then cycle repeats itself. ??? is this an engine failure starting, after car is warmed up oil light will sometimes flash briefly on/off but car is not low on oil.i thought poss fuel filter issue until read your post above. 900rpm and above no oil light? thank you in advance for any help.

toolpants thank you for reply,any other thoughts as to cause.this onlyoccurs under heavy acceleration.5000rpm or more if not under heavy accel runs fine no code pops.the nearest dealer 340 miles 1 way so am trying to rule out easy stuff b4 I make the trip

:) I pulled mine off this spring to have rear window replaced,100.00 fix.It is a very time consuming project but not impossible if you are mech, inclined .it took about 5 hours to remove and three to put back once new window was put in.NOTE if you have this done have upholstery shop install 3M double stick tape where clear plastic meets frame I found it very hard to find oe sealant/waterproof tape in any catalogue. you do not have to pull metal frame out. one of my plastic ball sockets for top raise/ lower was broke. fixed at same time. ? feel free to e mail me will be glad to share my experience. good luck mcd.
