So, I got me a nice 2.0i as noted before, and wouldn't you bloody believe it? The damned thing has the same sodding issue, low idle RPM with what sounds like misfires (thudding noise from the exhaust every so often). I've changed the plugs, no dice. Cleaned out the ICV, nada. Today was spent changing all but the manifold and the downpipe on the exhaust (I did the gaskets though), and still nothing. The 1.8 has this issue, even with a new O2 sensor, so I'm almost reluctant to change it.
The one thought that springs to mind is that of injectors. I don't know if either is overfuelling, but at the price that most injectors go for, I'm again reluctant to swap those out. It's just the idle, fer chrissakes... drops almost as low as 500 on the 2.0i, and it's really doing my head in now...
Also, I don;t rate EuroFlo exhausts... I can put my hand over the end of the pipe now and watch it blow condensation though the seams of the middle and back boxes...
Never use another Cav driver as guidance to a destination, unless you REALLY want to explore the country.
