Re: 166 3.0 V6 - shudder and loss of power
Since last weekend I 've been driving a bit constant speed low revs. Definitely, has an effect beacuse there is much less clicking from the engine than before and no more engine shudders. Before the clicks were every 2s now it can take up to 20s between two clicks.
Tried pushing it up to 5000rpm and I still get a loss of power.
As initially suggested by bobda, theory is dirt in the plug causing an arc. If it were the front plugs easy to unmount. Not in an urge to access the rear ones if I can somehow clear the "dirt".
