My OH has a cavalier 1.8 (petrol) which keeps cutting out. It is mostly on acceleration but not always. We have changed the carb twice, the fuel line, the petrol tank, added filters, bought a new pump and tried an electric pump. Some one suggested it may be the brain which we are going to try tomorrow but as you can imagine it is driving us crazy!!!!:shame: I think i have mentioned everything but we are total novices in need of desperate help. Any suggestions? Thanks, Shell.
