2350 after treatment problems

[Jskojo89]

Thank you, I'll try that tomorrow when I get back to the shop. I'm battling the flu at the moment lol. I thought it could be something like that, I read this systems can be real touchy. I know the driver had been running it since the overhaul with the check engine light on and never bothered to get it checked. So I'm sure I'm in for all kinds of fun. The story I got so far is the truck originally made it 600k and developed a antifreeze leak, the driver just kept on trucking until it overheated and fried the motor. Had it overhauled, but refused buying a new head. Made it another 80k then it dropped a valve and destroyed everything. So now it has 20k on a overhaul with a new head. Not to mention it's a disgusting mess inside and out. But thankfully I have a donor truck for the interior! Lol
