running rough-- help, wife is mad
It's time to post about my latest problem...
Wife's daily driver. 2000 Excursion Limited, 264K miles. Had 243K when we got it a little less than 2 years ago. Has run fine since then, stock aside from Edge Evolution programmer that was on it when we got it, and I did my favorite mod, the DIY intake/6637 air filter. 20K miles no issues, untill now. Batteries are about a year and a half old, replaced the alternator (6 mos ago).
Starts but runs rough, won't take fuel, won't rev up. A week or so a go, it did this, Edge went nuts, reset to stock BS, (even though it was already set to stock) no start, theift mode, etc. Was cranking slow, so charged the batteriies. Started fine after that. unpluged Edge completely (was only using it for gauges anyway).
Could weak batteries cause these issues? Have enough juice to start but not enough to power IDM and run it properly? Perhaps a weak alternator? I'm at a loss... plugged Edge back in to use it to read codes and now it won't even work.
Now, today, same thing. Will start, romping rough idle, won't rev/take fuel. Have drained water drain, no change.
What about CPS? I've heard they will just not start at all if it's CPS, not the type issues I'm seeing. I can rob parts from my yellow dually of the same year if it's an IDM issue, or anything else for that matter. What I don't have is any way to check the codes.
Please help me out here... wife is asking me why I can't fix it, thought that's why we bought a high mileage truck because I knew everything about them, etc. What I do know is how to ask questions from people who do know... help!!!!
