Hi Guys,

I'm a 'noob' so be patient with me. I have bought a 2004 C180 and I'm having trouble with a rough idle,i've had the MAF sensor changed (at a premium price) and still the problem remains, now I'm reading it could be a split pipe under the air intake maifold but I'm having trouble accessing it.

Can anyone point me in the right direction? I've removed all the bolts that i can see but it doesn't budge, a step by step guide with pictures would be brilliant if you could ��

Thanks in advance,

Daniel.
