Is scan tool saying anything ?
Rideandrepair and blairandgretchen Thank this. -
You could send it off to DCS - he opens them, repairs, reseals tests and tunes if you need.
He’s a bit hard to get hold of - he will get back with you, but might take a day or two.
I’d be inclined to get some Detroit software plugged in to it before you replace or repair. Just to see what’s going on.Rideandrepair Thanks this. -
Scan tool showed nothing abnormal.
Rideandrepair Thanks this. -
So even when you make the issue come on or off there is no codes ?Rideandrepair Thanks this.
