ever since i got my car back when i get into the high rpms its got a miss with little backfires or pops or when i shift into 2nd and try and get on it can feel them through the pedal ..its really bugging me cant figure it out far its got a new cap and rotor ...spark plugs .... everything in the sig is also new with just over 2000kms on them ....i think it may be the coil cause its old but i dont know ..any opinions ???
