6.2 replacing injectors

[towerrigger]

My 15 CC all terrain with 6.2 is in dealer having all the injectors replaced. 16 000km on it so far. Truck started to miss or feel like slipping with no CEL lights coming up when under hard acceleration on the highway. Initially I thought it was tranny slip. It gradually got worse then the flashing CEL came up. Took it in and dealer said they are going to start by replacing all the injectors. Parts on back order so may be a long wait. Anyone else experiencing this with the 6.2? Dealer just said must of been bad parts.

going to start by replacing all of the injectors? gotta love throwing parts at it.... what ever happened to actual diagnosis?

 

what code(s) set off the CEL?

[towerrigger]

They haven't told me the codes yet. It just gave me a flashing CEL under hard acceleration. Figured my cheapy code reader wouldn't pull anything. Manual said a flashing CEL was misfire.

That's usually what it means...

If it's under warranty let them fix it. But a misfire under heavy accel is much more likely to be a secondary ignition problem.

It could be a faulty coil....this happens to vw's alot. It really shouldn't be that hard to diagnose. I know I would also check the fuel quality. It's really rare that all of the injectors would need replacement.

Have you been running 91 octane or something lower?

[towerrigger]

Only ever seen 91 in this truck. Ran regular in my 13 6.2 but it would knock a bit. They ended replacing #6 injector and it has been good so far. Apparently the advisor doesn't actually talk to technicians. Advisor made it sound worse than what was needed.
