I have a 2015 Escalade 6.2. I changed the lifters ,trays,camshaft and the spark plugs. Now the codes that pop up and I can’t figure out are
P0300 “engine misfire” cylinder 4 misfire pops up and then goes away and says random misfire again
P0102 “ mass air flow sensor circuit low frequency “
P135A/B “ignition coil supply voltage circuit bank 1 & 2”
I changed the spark plug wire and coil pack on cylinder 4 because of the code and still the same.
I feel like when I have the vehicle on and take the plug from cylinder 4 the idle stays the same. P.s vehicle shakes as soon as it turns on because of the misfire
