SO i have a 2001 awm 1.8t passat and i am having a problem with getting a misfire to go away!
IT started with a random misfire on cylinder4 i then replaced the plug nothing happened and then replaced the coil and the misfire went away but sadly it came back for cylinder 3 then 1 and back to 2
so i replaced all the coils and the misfire still came back so i brought it to the dealership and they said it was my maf due to my KN filter so i bought a new filter and maf but the msifire came back shortly after driving it around for a day i just recntly chnaged my IAT and the new maf seems okay but now i havd a code for the maf having a high voltage rate
i just took the car out reattached the maf as i unhooked it and the misfire went away but as i said i took it out and i sawpped all the coil packs and never got one misfire but i only got like 2 pounds of boost when 8 is nromal and allmy vaccum lines are great shape
my codes are
P0300- random msifre saved
P0103- MAF circuit HI input
