Yesterday, our high was about 13 degrees and I had to make a two hour round trip to the airport. Even after 30 miles and everything warmed up, the engine sounded like it was going to jump out of the truck and head back for shelter.

The injectors were extremely loud under light to mid throttle and only calmed down during hard acceleration. For most of the trip, the truck hesitated and bucked while accelerating and cruising.

I've driven this truck at -20 and have never experienced fuel gelling. I'm also quite certain I have my first batch of winter diesel as I noticed my fuel mileage drop to 11.5 mpg average from the normal summer average of 14.

Has anyone else experienced issues like this?

No CEL? No WIF warning?

Nope. Neither of those. I even checked my Edge CTS for stored codes but it had nothing to show either.

Maybe just a tank of crappy fuel.

Loud injectors?

It may be possible, but this fuel was out of my aux tank. I had already ran 70 gallons of it through at this point. I had also put a bottle of Power Service into the aux tank when I filled it up.

Loud injectors?

Yep. It sounded almost like a 5.9.

Loud injectors?

Turn a multi injection injector into a single injection and they can get loud.


Most likely not what’s happening here though.

Did you maybe change or accidentally change your timing setting to "edge timing" from "stock timing" on your cts??
The edge timing will make it sound all cackly and act exactly as youre describing. Might want to check your settings.

Aside from that, sounds like a fuel pressure, lack of fuel symptom more than likey from a bad load of fuel or summer fuel in those temps, or a restricted/gelled filter.

My CTS is just a monitor, not a programmer.
