Hello all,
This weekend I noticed my S3 2.25 with a Weber 34ICH was popping and farting a bit and struggling to get up to temperature even with its muff (or gimp mask as my missus calls it) done up.
I suspected mixture rather than ignition and indeed the plugs were pretty sooty. As a first measure I turned the scew back in a couple of turns and have been letting it out since. The engine warms up nicely now and it doesn't pop and bang as much but it is a bit down on power....any advice on finding the sweet spot. Is one of the gas analyser things from Halfords worth buying...should I tap a Lambda sensor into the exhaust?
Cheers
Dom
