Hi all, i was out in the car the nite for a B road blast and ive notice that she has developed a missfire just before the shift light comes on. when this happens she holds back and when the missfire clears its fine. Its not constantly happening in every gear its just random. I reckon it did it 8 out of 10 times. If it could be plugs could you please recommend the best ones to go for. cheers!
