2001 6.0L really low idle all of a sudden

[zieg85]

Any update ?

Emailed the PO.  He said it happened once in a while and would clear itself.  I am more at peace that I have an idea of what it is and I will deal with it down where my tools are at.  I am still trying to return home from the Christmas holiday back in Indiana but we had real bad weather which put us a day or 2 behind.

Based on what you just said, it sounds typical of a throttle body that is beginning to become overly coked up. No problem, deal with it when you can. Good luck catching back up to schedule.

Went to start it today, no idle at first.  Had to jazz the go pedal for about a minute till it would run on its own, been fine all day, idling about 600 rpm.  Fingers crossed, ready to head 300 miles with her tomorrow...

I'de be willing to bet more than anything it's that throttle body. It's probably pretty coked up if it's never been cleaned.

Awesome trouble free ride home.  That is one comfortable riding/driving truck!!!

i cleaned my maf and my throttle body. seams to run a little better, dont think i gained any mpgs might of even lost some lol. this thing gets worse millage than my 94 with the 4.3. hows yours working out?

Can't drive it with my latest situation...  Have no idea on the MPG since it only has about 300 miles on the tank.

300 miles and no fill up? mine has 25 gal tank im getting about 14

Thinking this one has a 34 gallon tank.  The previous owner said it would get 15-17 without a trailer behind it..

i dont know why gm would even put a little engine in a truck when you can have a bigger one with more power and better mpgs. its like selling false hopes cause you know someone is going to look at the 4.8 and think "this engine is the best of both worlds and should get better millage than the 6.0"

[Irish_Alley]

dont mean to hijack but i added fender flares to mine and she looks like a new truck (almost)

but hows yours been running?

[zieg85]

Been OK running but now that I know what it is and that it eventually clears itself I am not worried.  Waiting on the UPS guy on a delivery from Crutchfield...  It would be nice to have some tunes in the truck

Those fender flares wouldn't happen to be doing double duty and covering up that dent in the left rear fender right at the top of the wheel well?

[Irish_Alley]

lol yup. while i was looking at flares i saw the chrome ones but theyre only about 2" and wouldnt cover up the dent and rust on the other side. i was thinking about replacing the bed to get rid of it. but now after $50-$60 problem is fixed for now, may have to take them back off to patch the rust

I knew it lol I could have bet money on it...
