Ive just got a sierra 1.8LX Greg,its done 168k,its fair condition,some old boy as had it for the last six years doing 3k a year in it,had a slight problem with the brake lights but that was sorted no problem,in 2nd gear it seems a bit lumpy ( if thats the word ) i thought maybe new plugs ? any advice would be really helpful guys....thanks :rolleyes:
