Got a 2002 S-type R thats flagging Bank 1 and 2 running lean, this can be seen when reading both number 1 lambdas which are just sitting flat at 0.2/0.3v's
Know this will be down to a Vac leak I know but which pipes are common to split on these engines? Only picked it up today and went into limp mode on the way home.
Cheers

I wanted to share my experience with you all. I got po171 and po174 on the ECU. I cleaned the MAF sensor and checked the pipes for breaks but everything seemed fine. The idle was rough, sometimes even stalling when stationary. I could hear some hissing sound coming from under the manifold so decided to take it to the local garage. After inspection they confirmed the problem to be linked to the inlet manifold gaskets. They also asked me if I wanted to replaced the plugs while the plugs were exposed. It seems that the garage who did the previous service only replaced half the spark plugs . Apparently a lot garages don't change the sparks plugs covered by the manifold due to the extra work required.
