hi all!! i have a friends truck that has a random rough running issue, so far only once. he stated he drove the truck, parked it for a few minutes and when he went to restart it on fire up he herd a loud pop and the truck started and ran but wouldn't idle and had a bad miss. he drove it home and parked it then started it the next day and it ran completely fine and normal.

the truck has really low miles and he only puts like 500 miles on it a year. here are the codes i was able to get. hoping i can get some insight on what they might mean and if he should just drive it more to see if they come back.

With three codes leaning towards a faulty CMP. I would start with the CMP (cam sensor). I could be on its way out.

Yeah, I would start there.
Could give the idm a good shake. Listen for water.

thanks guys. ill give that a shot and have him drive it some more. hes an older guy and its like he tries to not use the truck and just lets it sit, i think he said it sat for almost 5 weeks and might have been when this happened. i told him he just needs to drive it more lol, like really drive it.
