Here's the scenario.
Puling with my '06 3500 5.9l megacab a trailer at 9300lbs over the cascade mountains on longer trip.
Twice I've thrown a dash light for the coil / spring looking idiot light and have gotten mixed info on what the light means.
This only happens after a long climb and several miles after the decent on the downhill side of a pass.
Bells go off and the light comes on...since I'm on the downhill it's not noticeable on power loss...but on a steep incline it's obvious the power is not where it was.
The light stays on and truck feels slightly underpowered...but definitely lacking power when pulling up a steep hill. After about 2-3 times of driving the truck the light goes out and power restores to normal.
Some have told me it's a grid heater issue. Others have said glow plugs (which doesn't make sense while the truck does fine until on a descent).
I've also been told it's a fuel issue after the transition of using lots of fuel and then letting off the pedal on a decline.
Anyone have an ideas what it could be and then more importantly...how to fix it??
Gotta get this figured out and fixed before I pull again in a few weeks.
Won't be much fun having power issues while climbing.
Thanks all!!
