Proton Savvy 1.1 petrol engine ok, stop laughing After driving around 15-20 miles, when either slowing down to stop or turn or idling whilst at traffic lights/junctions, it will just cut out. Engine will turn over but not catch. Doesn't happen every journey, 1-2 times a week. What seems to get it going again is spraying WD40 or Easy Start into the air inlet pipe, it won't fire up straight away but after a few go's. Just got back from the garage, having left the mechanic scratching his head. He's looked at everything he can, leads, sparks are fine as is fuel filter. He couldn't replicate fault so diagnostics just showed everything running fine. It's going back in again when he and I have the time for him to take it on a long run to try and replicate the fault, but if anyone's got any ideas (apart from burning the car out), I'd be grateful to hear them!
