well i relplaced my afm sensor today and the car started up n stuff but sounded like it was kinda bogging down..i think this is normal im not sure..so like i let the car run for about 20min then went around and drove it..i could drive it but every time i gave it like a little gas it would kinda bog down..is this normal? i have my car runnin outside rite now hoping that if i just let it run the gas will burn away and it will be fine..i need help ASAP..thank u
