I have a 98 volvo v40 which is generally very reliable. However, for the
past 2 years the engine start racing when idling or in 1st or 2nd gear and
a lot of black smoke comes out of the exhaust. The only way to stop it
racing is to put the car into neutral and press the accelerator or to
depress the clutch very slowly. This has been happening only occasionally
ie about once in every few months however I went on a long journey over
the weekend and stuck in traffic on the motorway this problem kept
reoccurring. When it was happening occasionally, I brought the car to two
different garages but was told that they could not find a problem as it was
happening only intermittently. Has anyone got any idea of what this could
be please?

Thanks

Shermy
