2nd Generation Dodge 24 Valve Powertrain

So to start here’s what I’ve done to try to fix it. Checked all grounds and connections, new batteries, new timbo apps. I don’t have any fuel pressure gauges so I don’t know if it’s a fuel thing. I am looking to get some today if I can. So the problem is once I get to about 43 it starts surging. It will stop as soon as I go back to 40 or under. The problem seemed to appear after I replaced my whole A/C system. And only when the Ac is on. But will keep happening even after the AC is turned back off. But if I never turn it on in the mornings, it doesn’t seem to do it. Although I never get too far about 15min before turning it on because of the heat here. It seems like when …

Truck surging wot with J/A lvl 5 and 6, any thoughts? Doesn't feel like transmission slipping and my fuel guage is installed as of today (waiting on parts:cry:). RPM's are in sync with surging and not running away...

Fellas, I know this most likely has been talked about and maybe way way back I even started a conversation on it, but my surging is back and i'm looking for thoughts. All summer my truck seemed to work fine with no surging, now that the weather is getting colder , i'm starting to feel it alot. Today it's about 4-5 degrees out and when driving along trying to hold a consistant speed I feel it surging up and down. If I use cruise control it maintains speed with no surging. I'm running 16-19 psi for fuel pressure always , no codes showing in the odometer. I remember last time I had issues I did a reset on the apps, even adjusted the voltage on it, took the IAT sensor out and…

Sorry it's so long, and it dose not start getting bad till the end. If you can see the tack you will see it surging up and down. http://jlweldingtx.com/JoesTruck/truck.html

It surges when eng is cold and after it warms up it seems fine. It reminds me of a tank half full of water, you feel the push then it drags back. I just installed new vp44, new injectors, crossover tube o rings, new airdog 165. Talked with Lenny at DAP and he suggested hooking up Iquad and see what datta it might show. I havent installed the Quadzilla Iquad yet because of this. I also just reset my apps a few minutes ago to see what happens in the morning. A real head scratcher, I hear about ecm's doing this but its always when it heats up, or the vp doing this as it heats up. This gets better as it heats up.

Tracked my surging down to the speed sensor my truck runs perfect with the sensor unplugged but of course no cruise control and annoying lights I've replaced the wiring and senor already anyone have any ideas? 2001 h.o. 6 speed fass 150 edge juice with attitude

Hey guys, I hope everyone had a nice holiday season. I believe that I have another random electrical gremlin but not sure where to start. So, it started the other morning on the way to the office, the truck started randomly surging as I was cruising down the interstate. I was traveling between 65 and 70mph, and it feels like the truck is accelerating on it own. I can hear the engine raise RPM’s about 100 RPM and I can feel the truck accelerate for about .5- 1 sec, then it goes back to normal and then it happens again. It is totally random, sometimes it happens at slower speeds and sometimes it only happens when driving at highway speeds, and sometimes it does not hap…

I just made a run from northern CA to southern Oregon. All was good on the way up but on the way back I noticed some surging, especially when at light throttle on flat road or off the throttle going down hill (coasting but still running 2000 rpm) . I switched tunes from my MoparMan mileage tune to the tow tune and no difference. I also hit the overdrive button and no difference. Fuel pressure was always 15lbs or more. By the time I got home I had a check engine light and it was 0236, Map sensor. I have cleared the codes numerous times and I might get away with driving a hundred miles or so with no code but the surging continues. A day or so later, the code comes back. …

Newby here again. This site is awesome,thanks again guys!:thumb1:I have a buddy that is trying to sell a 12v with about 175,000 miles on it, and with all the trouble I seem to be having with my 24v he mentioned that maybe I should just swap them out. How big of a project would this be?Is it even a smart move? I would really like to get the 24v going just for the education but I really need to get this truck on the road soon. I have to let go of my Toyota soon and need this truck running before I can do that.

After weighing out a new paint job cutting and welding up the top and new glass, hood, bed, fenders and hood it looks easier to swap trucks? It seems a gas 2500 4x4 manual is way cheaper then the diesels ones are. SO is it a real big job to put my running diesel and 6 speed into a gas truck and use the parts off my diesel to beef up the gas power train? I have the complete power train and a great looking dash for all the electrical. Then I could part out the rest of the truck to cover some of the costs. I see 2001 Dodge 2500 4x4s going for $4,500.00 with nice bodys and interior but high miles on them. I could not get a good paint job for that price let alone all the body …

Hello;allow me to introduce myself,my name is ed and I hail from manitoba,canada.I have been lurking on this and other forums for a while now,looking for info on a project I was roped into.I have a tech question and am looking for assistance:I am in the process of attempting to install a '01 24v into a '99 ram.The '99 threw a rod.I have run into the problem of the lack of a crank tone ring on the 01 engine.I had planned to do the crank swap but it turned out that the '99 crank was cracked and junk.So here is my question:I have read that it may be possible to change the '99 harness so that the crank sensor wire is re-routed and connected to the cam sensor on the '01 engine…

I have less than 10,000 miles on some DAP 50hp injectors but as many of you have said, always go bigger! I purchased some DAP 8 x 0085/100hp nozzles and put them on my stock/factory bodies that had less than 60k on them. A local FI shop checked out the bodies, installed the nozzles and popped them at 310. The increase in power going from the 50's to the 100's seemed greater than going from the stockers to the 50's. It has a nice little puff of smoke when you get on it from a standstill but is otherwise smoke free. I really want the power to kick in when needed up at cruise speed and I'm trying to pass some farm truck on the rural highway that is doing 53mph ( I call it th…

What is involved in replacing the nv4500 with the 6 speed? I cant keep a 5 speed evidently, I believe they just skimp by on parts or something. The only other thing I can think of is I'm running the amsoil synthetic.

Well my d70 decided to commit suicide today so I went and bought a d80 i got the u bolts axle plates blocks overloads ect what else needs to be done any one ever do this swap I have a 01 auto qcsb

I'm going to try and start gathering parts for my tear down, and would like to replace all of my synchronizers while I'm in there. 3rd and 4th gear are getting pretty tired. Does anyone know any good places to source these parts? I don't want anything cheap that will go out in a year. Thanks!

Did a clutch swap in my NV5600 and lost some of the fluid. I just changed the fluid last spring so would just like to add to it to get the proper amount rather than draining it out and putting new in. (Fluid still looks clear) No idea how much I lost so don't know how much to put back in. Top it off until it comes up over the gears be a stopping point or is that too much? I should add I know theres the plug on the side to check, but I cant remember how far up past the plug it went last time I put the extra bottle in..thats why I ask the question thanks

What should I plan on spending for 3rd and 4th gear syncros? I will need to have a trans shop do them as my life currently doesn’t allow me the time.

Well Chuck... How is the AMSOil Synthetics working for you? I've got lots of people asking about using synthetic 2 cycle oil in the fuels but I was uncertain of the results you've gotten so far. So I'll let you continue this thread for the others... But I'm curious myself of the results you got so far! 8-)

It is getting hard to find non synthetic 2 stroke oil in the Houston area. Where are you finding "regular" 2 stroke oil? What bad things happen when synthetic 2 stroke oil is used?

Winter is around the corner we get to -40 farenheit some days ,I was thinking about going with Lucas 75w140 full synthetic instead of 85w90.the front diff is a M60/2 and rear M70/26 with anti spin.
