oh also when you take off from a stop light it kinda jumps and when you are going down the road and take you foot off it slows down like your foots on the brake and when you barely touch the gas it jumps

Re: cel code p0505
it def sounds like an iac problem...id try cleaning it more..also make sure that the coolant is full because coolant runs trough it and if its low it causes idling to be erratic
