I wonder if any of you guys may have an answer to a really strange fault that my better half's 2001 1.4 Corsa (B?) has had lurking for a while now.
The wife very rarely drives far or fast, fast being more than 40MPH and this fault does not seem to occur then.
BUT when I drive it on a longer journey and at higher speeds, around 50 - 60MPH (all within the legal limit I hasten to add!!) the problem occurs.
It begins once the car is fully warmed up and travelling at about 50 - 60 MPH when you can feel the engine begin to hesitate and jerk. If when this has occurred there is a need to stop at a junction the car will stall and will not restart without difficulty. It is almost like the engine is overfuelling as it coughs and splutters and after some persuasion will then run. After this has happened the fault most times seems to clear and the car then runs OK. Sometimes it will continue to cough and splutter for a while but eventually clears itself. No codes are stored (I have a code reader) and no lit EML although the last time this happened there was a flashing EML (only ever happened the once) that cleared when the ignition was switched off and then back on.
Any ideas would be most welcome. Could it be a temp sensor, EGR prob etc etc
