    Default emission light, car bunnyhopping, help?

    I would love some advice-Ive had my vectra for just under a year, not a problem, treat it very well, 140,000kms, 2.6, auto, always use 95 petrol..

    today was driving along as normal and I stopped at traffic lights, then as I took off, the emission light was flashing and the car was struggling, started bunnyhopping
    still driveable but I got it towed home to be safe...
    Could it be a fault with a sensor?

    thanks

    I just looked up what the pedal test was now, no I didn't do that but I'm glad I know what it is now..
    The roadside assistance mechanic said cylinder 2 was misfiring...

    he plugged the computer in and thats what error came up...my actual mechanic changed the spark plugs, wasnt them, fuel injectors, wasnt them, tested the actual fuel, was fine..then he said the car would sometimes be ok (he's had it for a few days) and then would misfire again...and he also said no3 has misfired occasionally too so he says coil packs :S
    they're pricey too i hear
