So i decided to change the spark plugs after it was misfiring, its now pulling alot better without jerking but as soon as i started the car with the new plugs in it seems to struggle to breathe properly and sounded like it wanted to cut out. It drives fine, just when its in idle this happens when the engine is cold and hot. Ive been reading up other threads about people have idle probs but couldnt figure out why my car never done this untill i changed the plugs? could it be the afm on the way out or lamdba sensor or map sensor? I dont want to put it to vauxhall cus there its been in there the past two months twice to try sort the boost and both times they never resolved it and overcharged me!!
Help me please!
Thanks in advanced.
