100% the truck has a mechanical throttle. its an 8 stack setup, there are no vacuum accessories to leak as some have eluded to.
if i had to guess on what happened, i would bet he hit the throttle and brake at the same time by accident, or a water bottle or some other foreign object got caught...
worked on countless tunnel rams that had bungs welded into them.
do your throttle bodys have injector bungs? i know holley has some 4 barrel types that have 4 bungs, two of these would make a nice setup other then they flow way more air then you would likely need. proper throttle linkage would...
for any cell based internet, it all boils down to how close you are to the tower. closer=faster.
the internet at my shop was so bad i could barely get 10mbs.
with my PC tethered to my phone and about 1/4 mile from the tower..........i can easily get 250mb. i just ran a fast.com speed test an...
depends on what ecu you use.
most dashes are fairly rugged so you wont have any issues there. the holley works properly if you use a holley ecu. if you have a GM ecu, that is more challenging and may require external sensors. in this case i would go with Motec.
i had a buddy who had the same problem.
FWIW, your pile of shoes is amateur status.
his house had multiple large walk in closets. every one of them taken over by her with hanging clothes packed so tightly, it was hard to even tell what was there. then in the middle of each closet, a SIX FOOT...
ran both on my 2500 mileage was maybe 30k. they got very noisy as they aged, even though tread wear was good.
running General's now and HATE them. sure i have one that is egg shaped or something based on how the truck shakes only from 70-75 maybe 10k on them. tring to resolve that now.
just...
you start by eliminating sesnors/connections that would stall the engine. This would be crank/cam sensors or a MAP sensor. could also be a bad fuel pump relay or associated connections. could also be a faulty idle valve. i would start by swapping all of these sensors from one engine to the other...
actually, nowadays, you need FOUR.
fuel spark and air.........yes........But an EFI engine........lots of electrical connections, sensors and wiring all working in unison are a must. having seen the Ilmor harnesses, i would not be surprised if there is an intermittent electrical connection...
there is a long history of this. my 08 2500hd rattles like crazy going over bumps etc unless on the brakes.
you can search GM/chevy forums and there are lots of people experiencing this. seem like new OEM brake pads resolves it.
