Hi
I have 2012 Trophy 2.0 litre petrol auto sedan with around 94,000 kms on the clock. I use standard unleaded octane fuel. Vehicle is fitted with cruise control (cc) and air conditioning (for hot Australian summers). The vehicle has been regularly serviced by myself (including new oil air filters and spark plugs) and has been returned to the hyundai dealer ship several times to receive software updates and satisfy recalls. Recently installed factory timing belt and pullies.
It's starting to annoy me now and I don't want to cause any ongoing issues, so for quiet some time, I've noticed that the vehicle seems to, well "hunt" is probably the best word to describe it.
For example, when driving down a freeway, with feathering or light pressure on the accelerator pedal, I can feel the car lurching slightly, as if its starving of fuel. In cc mode it seems to be fine.
I've replaced the 3 ribbed o'ring/seal that fits onto the air intake pipes, thinking it might be drawing in to much air. If I plant my foot on accelerator, it kicks down a gear and takes off.
Can anyone advise what this mysterious problem is. TIA
