Strange Electrical Gremlin

Alright I’ve had enough I can’t take this surging power anymore. 2004 Ram 5.7 rwd, I’ve been having surging issues since I got this thing years ago after totaling my pristine white one, it’s weird it’ll surge for like the first 10 minutes of driving and if I’m going slower sometimes it’ll just completely die, after the 10 or so minutes mark it’s absolutely perfect with no problems. I’ve already tried 2 reman pcm’s reprogrammed for my truck, cam and crank sensors, o2 sensors, map and iat sensors, trans speed sensors input and output, trans pressure transducer sensor, and 2 different throttle bodies. All the named sensors except o2 sensors are new from ngk, the o2 sensors came off a 08-12 charger(they’re the exact same sensors) for similar reasons but didn’t change anything so theres nothing wrong with the o2 sensors, 1 pcm was from flagship1 and the other was from all computer resources or whatever their name is(it fixed my white truck). I remember having the scanner hooked up while trying to check tps as well as trying to see if it was missing at all a while ago and it wasn’t missing a lick and tps was functioning fine. That tells me that surely it has to be electrical since it seems to figure it out and run perfect after about 10 minutes, and if you simply cut the truck off and back on it’s running like garbage again restarting the learning process of whatever the hell is wrong. Hopefully someone has unfortunately had the same issue or has the answer cause I can’t take it anymore. The engine itself actually came out of my white truck so that also makes me believe that it has something to do with the bee truck as a roller like I bought it instead of engine related. The things I know for a fact it needs is a cluster and maybe a bcm, is there any random possibility that either of those could be the problem even though unlikely? Also what about the TIPM and FCM, my mothers 12 ram was fried from a lightning, I know because I was less then 50 feet away when it happened, I jumped higher than Willie Nelson gets daily it scared the hell out of me, anyway insurance ended up paying over 5k to have it fixed and among the problems was a TIPM that is said to cause similar issues. Once again sorry for my novel I just wrote but I'm sick of this never ending problem Thanks in advance for any help whatsoever.

Did you ever figure out the problem, my 04 5.7 is doing the same thing.

Mike, that is one hell of a thread resurrection!
I'm sorry for you troubles.
My wild stab-in-the-dark, low-info answer is perhaps a fuel pump issue?

YES the EGR. Fixed it several months ago now and am finally able to enjoy driving it again, it still may not be your problem but it was mine. I would have never thought in a million years that it was causing it all but it was on mine. A guy in another group threw me a huge bone when he told me to check the EGR valve. It’s free and easy to test it too, simply unplug the connector to the EGR valve and then go for a drive and see if it fixed it, if it stopped the annoying crap then you know you need an EGR valve, you can leave it unplugged until you get one or you can just leave it unplugged forever, they’re pretty cheap and easy to replace though so I just replaced mine anyway, get one that comes with new gaskets but reuse your stock bolts the new ones stretch and snap incredibly easy and use lots of wd40 or kroil before trying to loosen the exhaust tube bolts they like to snap too

Good advise. And glad to hear of your success!
