Hi my car keeps cutting out when i come to a stop it drives fine but when i stop it just cuts out, i recently just had a full gaskest done new egr valve,reason for the was it was burning oil and had a strange rumbling noise come up the air filter and sometimes went to cut out when i stopped but didnt. now thats all done,its got worse and does cut out,but starts first time after it does! No engine mangement light come on, the car runs fine when driving. Also sometimes when idleing it can sound like its miss firing and sounds like its running rough. does anyone whats up?
