Accidentally rev while cold

Recommended Posts

I just got a 2004.5 LLY duramax from a local gmc dealership and it is a great truck so far but there are some minor problems. One of which is the gas pedal is cracked and the spring is ghetto rigged so you can still use it. When I was starting it this morning, I was trying to set the high idle and after I had set it I turned the truck on and the gas pedal was stuck down and the truck revved to about 2800 as soon as it turned on. Should i be fine? Or should I go get it checked out?

No worries.

Unless you hear a problem.

You bought it this way?  You could just replace the pedal mechanism, but I would be more concerned with that level of repair throughout the vehicle...

wouldn't worry too much.  Many diesel engines for emergency power generators rev up immediately upon start.  Now.. keep it maintained and oil changes and such

What am I missing?

I always just left the elevated idle 'enabled' on my 04.5 LLY.

 

It only kicks in when the necessary conditions are met. (so on warm days or with warm engine it does nothing)

 

Occasionally I'd get after starting I get distracted,  it would idle down once the coolant was warm, and re-engage the elevated function again if it idled long enough to cool back down. 

 

 

And I agree about correcting the return spring and pedal -- before someone gets killed.  

As the first post indicates, it will bite when least expected.
