Hi All, Looks like it's been a bit quiet on here lately. All those ZXs can't have gone to scrapyard heaven yet, can they? Anyway, got an idle problem on a ZX turbo diesel. It's a 97 ZX SX TD, 170K miles. The idle rate has suddenly moved from 950-1000 rpm to 1150ish. The rev range seems spot on at higher revs so looks like the idle setting (or something that can influence the idle rate) has altered. It happened about the same time as I hit a particularly nasty pothole. Fuel consumption may have increased slightly, but can't be sure at the moment. The car feels marginally rougher, but again
