This is the problem that has beaten my garage.
Car-Accent 1.6 CDX 3 years old
The engine check light has come on twice in three days and flashed for about 15 secs each time. Both times it occurred after just over a minutes driving from cold. The garage checked the error messages and it said ?Random misfire on cylinder one, and on two, and on three, and on four?.
They took the car in for days and checked everything that could be checked, but came up with the answer that all was perfectly in spec and that nothing was wrong.
Can anybody help by suggesting what could be wrong with the engine. Any serious sleuthing would be very welcome.
