2010 silverado 5.3L
My friend changed his intake on his truck and replaced it with on off a 07 silverado and also replaced the mass airflow also. It started up and when he reved it and idled down it sounds like it got stuck in 6 cylinder mode. Engine light turned on and codes came up
P0443
P0103
P0443
C342D
P0055
C3064

 

Put the old one back on? And pull the negative cable off the battery for 20 minutes to clear the codes ... Heck I don't know ... Ha

Have u looked up the codes ?

 

Its back to stock and it still does the same thing and we have checked everything and we don't know

 

so you are saying you installed an 07 MAF sensor on our 2010? i bet you popped a fuse, they are not wired the same at the MAF harness.
