Engine dies while muddin...

[Redboy4457]

Hey guys, I have an old '84 Silverado with an LQ9 and 4L80e. On the street it runs fantastic. Couldn't ask for anything more. The trans finally got tuned in real good and its a great DD. We recently have had a lot of rain here in Illinois so I decided to take my truck out muddin. It was running good until about halfway.

Problem - I feather it a lot when Im out on the trails, and I believe I was causing the motor to flood. After I would take it either through a mud pit, or a trail and would stop feathering it, it would start to run real rough. And if I left it, it would get rougher and rougher. If i shut the truck off for a little bit (10-15 seconds) and started it up it would start to run fine. It continued that until I was done and opened her up leaving the pit. Ran totally fine rest of the day, and today.

Just wondering what I can do to solve that/ help with the problem.

Sounds like you got the MAF dirty to me. Fuel injected engines don't just flood unless something is screwed in the tune.

Post up the file and I'll browse through it.
