I replaced the EGR VALVE  BUT IT still hesitates when giving gas and it missfires when romping on gas to get on highway so what should I check now

Answer 1

P0102 MAF sensor circuit low frequency

What can set a P0102 may not even be with the MAF sensor, vacuum leaks can cause this code to set, a slightly open EGR causing a vacuum leak can cause this code to even low fuel pressure
