is your brake booster leaking vacuum? also the pedal goes quite low on a vacuum booster but always bled the entire system several times until fluid is clear with no bubbles in the line.

I definitely don't know about brake booster leaking vacuum, but surely it was working fine before doing the rears(aside from pulsing pedal) must have something to do with the repair? Is it possible that if there's air in the lines that could cause the shut downs?

Also I recently added a few ounces of seafoam to Tank yesterday, with about 5 gallons left in fuel tank. I know it's obviously reached the engine, seen some heavier smoke when starting up. Could this be causing the idle to drop enough to sit truck down?

 

[SunlitComet]

bleeding the brakes no. the seafoam maybe, what color is the smoke and does it happen only at start up?

 

[joeshark]

Seems to have only happened at start up, I'd imagine it's the seafoam doing is thing. The snow seems gray I guess.
Also seems like the stealing issue has gone away, so I'm guessing it was also because of seafoam concentration in small amount of gas?

 

[SunlitComet]

might have been effecting fuel air mixture to much. watch it.

 

[joeshark]

I was thinking now that I have a full tank of gas, I could run a half bottle of seafoam through?
Seems as though motor has a tiny little stuttering, figure might be time to do tune up?

 

[SunlitComet]

if the smoke is gone then maybe do the seafoam again with a light dose. burn it out and reexamine the engine performance.

Thanks Sunlit. I've noticed that smoke happens daily after starting car, then it's gone after 10 seconds. Is this normal for a big truck like this?

if you have emptied out the tank and really diluted the Seafoam that was in the tank then you should not be seeing smoke any more. check all your fluids and make sure nothing is low in case you might be burning something. check the color of the smoke again. assuming there was no Seafoam used at all what you describe is leaking valve stem seals most likely or possibly the injector are leaking a tad bit at start up. take some more notes and pass on as much detail as possible so we can find the issue.

Thanks sunlit will monitor.

I'm also having an issue with heating/AC airflow output. I don't think I'm getting any air through the vents in the first 3 settings. Only in high do I hear the blower going.
I'm attaching pic, could this box have something to do with it? There is tape apparently trying to seal this up. I'm not sure if the air is leaking through there or if this has anything to do with it? Or if something wrong with blower motor?
