I have a 1998 1.2 16V Vauxhall Corsa Breeze. It recently started to bunny-hop at low speeds and threatens to cut out (but doesn't). Took it to my local garage who diagnosed a faulty or dirty egr valve. They replaced this (at some cost) but it hasn't solved the problem. Another suggestion has been the idle control valve. At this stage I think a new car would be a better investment! Am I wasting my time and money?
