I have a 03 CLK 320 with 32k on the clock and I have a bad miss bad
idle and stumble that starts up when you hit 3k on the tach and on goes the check engine light I did a scan with my Snap-on Modis the code I came up with

------------------------------------------------------------------------------------
P2051 Misfiring of cylinder 1, damages Twc currently valid strip (P0301)
-------------------------------------------------------------------------------------
same for cylinders 2,4 and 6 I changed all 12 plugs and wires and cleared all the codes out to just have it start doing it all over the only other thing that i know of is both resonators have a internal rattle if that has something to do with it

 

ps I did clean the mas air and have 2 new air filters

 

coilpacks?

 

How did you go about cleaning the MAS? They are easily ruined in the process. Just sayin"

 

With soap and rub it with metal sponges.



































J/K.....there's a product spray specially for MAS. You just spray it on and let it dry off.

 

I used specially spray cleaner for MAS but it was realy clean

 

im thinking coilpacks my self is it possible for more than one pack to go bad at the same time

 

ok i have all new plugs & wires and the #1 coilpack and still have a miss code once the
engine light comes on im showing a miss on 1,2,4 and 6 im going nuts with this
