My Avalanche Stalled

[james21]

I have had my AV for 25 months roughly, and the other day my AV stalled for the first time. I am guessing the reason is that the computer reset itself when I disconnected it. It was during my install of my new stealth offroad bumper. After it was on and the winch/lights were hooked up, I started it up and noticed that the engine was struggling a little and then it stalled. I started it back up got it outside and was running it, and again it sounded as if it would stall, but I decided to gas it a little and it sounded better.

I do have to say that I think that I should have disconnected the battery every time I did and engine/exhaust mod, so that my computer could re learn. Also I noticed that the new bumper slows me and my LEAD foot down quite a bit.

Fuel filter, maybe?

mine didn't come close to stalling, but it did run fairly rough for the first few minutes after the battery disconnect.

Mine did this after I was messing the the fuse box to trace a problem I put my prediator on the truck and it said I had a mas air flow sensor problem. I am guessing I glitched it when I opened the fuse box. The truck did stall but the 2nd time I reved the engine it was fine. Cleared the code and restarted fine.
