Hi Richard,
It's been a couple of months since I last logged on; sorry I missed your private message!
I see that the spraying has got well under way! The white has broken up the bay nicely! Yes, I used spray paint for the engine bay plastics. I used U-Pol Professional in matt black with a U-Pol lacquer. I like the U-Pol stuff because it's in a higher pressurised can, so you get a nice even layer. However the Halfords paint is just as good, and as long as the paint is thinly applied and given adequate time to dry between layers, it'll stand up well to the heat (if pooled it can bubble under heat).
Sorry to hear about the colour match issues. Ovni is such a difficult colour to match, because it's prone to heavy fade (as we both know). If I keep my car, I'll have to go down the route of a full respray to get it all matching perfectly. Been there with the colour match issue and it's a kick in the slats!
I had a coilpack go on me earlier in the year. Over the course of the 30 mile drive home from work it started off when I gave it a bit of poke and then progressively, even under part throttle, it became more pronounced until it ran completely rough, as if a cyclinder had gone. I replaced them with the Beru coilpacks from Eurocarparts. Think they were £27 and came highly recommended. If it's not a boost leak, fauly spark plug or throws up a fault code on the maf, it might be a ??coilpack that is slow in giving up?
Hope what ever it is gets sorted soon!
James
