My truck is a 1998 silverado 5.7 and I'm.chasing some issues , first the codes are P0300 random misfire, P0102 , P0108, P0122. So in the beginning the truck would just crank over and would shake and try to run , so I started unplugging sensors and nothing changed , well it just so happens I forgot to plug back in the map sensor and she starts first turn of the key , could all these codes be related to the map sensor? Thanks.
