New Member, New Truck, Two Questions

[Sierranick]

i have purchased a 2007 sierra 4x4, new style. (5.3, 4 speed)

its awesome, i love it, its my first GM product.

 

ive done a ton of searching, but google is letting me down on both questions:

 

my first question, i seem to only have 2 backup sensors, the middle two are capped off in both the bumper ( plastic plugs) and on the wiring harness.

is this normal? or did the previous owner do this?

 

secondly, my abc computer is toast, it ate a rock once upon a time, and water got through the crack in the case and killed it. ( i know, i took it off the pump assembly it was full of water and grit.... which explains why the guy pulled the abs fuse( the pump runs all the time when you put it back in) )

 

anyway, i know i need to replace that.

the part i need to ask about is when im braking, when im almost stopped, im noticing a slight shudder, and my tach is showing my rpm's bouncing a little bit. ( from 400-500 to about 800-900)

once ive stopped it idles normally.

its throwing no dtc's

ideas?

 

thanks in advance.

1) those cameras probably dident' come standandard on your truck so they just replaced the camera's with plugs

 

2) the bounceing of rpms could be the trans downshifting

Nick, welcome. But that looks like three questions.

 

BTW. Im not sure of the answers.

[Sierranick]

you win, its three.

 

 

the backup sensors are factory, or at least factory installed, its on my spec sheet as an option ( i went to a dealer and got them to print it out using my vin)
