. I was attempting to cross a small ditch that had some standing water and bottomless mud. In my own defense it was dark and I didn't see the water due to the tall grass. I tried to rock her out but it was a no go, the water got up to the bottom of the drivers door frame before we hooked up and pulled her out. She fired right up after that and we drove back home. On the way back she wasn't running 100%, some sputtering going on but otherwise ok. I took the hose out and washed all the mud off and called it a night. The next morning she wouldn't start, I'd get a little pop here and there but that's it. I pulled the cover and gave her a look over to make sure water didn't get into the Distributor (pertronix), intake, or on the plugs. All that was good to go, the only evidence of water intrusion was some mud splatter on the bottom of the first 2 valve covers. Three things that need mention. 1. The same day I got stuck I noticed that some welds had cracked on the exhaust in front of the heat exchanger, so I purchased the flex kit from SAV but that isn't supposed to arrive until Wednesday. 2. While I was trying to get out of the ditch the welds broke all the way through and my exhaust leak went from a small crack to full on open headers. 3. I hit the 4500 RPM limit while trying to get out..
So my first thought is I probably need to check my 4500 rpm module? After doing some searching it seems like when the module goes bad the engine won't run correctly. My second question is could the lack of back pressure on the exhaust cause the engine not to run? That would really surprise me but I'm open to all possibilities at this point. The truck was running tip top before I got her stuck.
