My 1.0 L Corsa does not idle very smoothly. Whilst stationary the idle speed tends to dip briefly every 3 or 4 seconds before picking up again.
I replaced the spark plugs as they were due for a change but this made no difference.
Also, it tends to struggle above 60 mph & I hear rattling from the engine when pushed to 70 mph.
Could this be a problem with ignition timing or is this normal for a 1.0 L car.
