2nd Generation Dodge 24 Valve Powertrain

I have an 01 Cummins and in the mornings down here in Florida when I start the truck up it idles rough and smokes for awhile. Any clues. Ive changed the cam sensor and filters. The fuel pressure guage says @ idle the truck has 17-18 psi. When i plug the motor in for the night and crank it the next morning the truck doesnt run rough, but without it , it runs rough??? I deleted the grid heater years ago but, this just started acting up. I dont think its because i dont have my grid heater in. Maybe the 110 BD injectors I put in the truck 4-5 years ago are clogged maybe?? how do you check them?? :ahhh:Got any clues?? Any info would be greatlly appreciatted!!!

I recently had the high idle enabled on my truck, as a matter of fact, I haven't driven the truck since I did that. I went out this morning to start it and it had a heck of a time firing. It would try to start, catch for just a second and then die. I cycled the grid heaters a couple of times, not sure if that helped. It finally did start and it ran like a pig. I've never seen, first hand, a truck run on 3 cyl, but I imagine this was it. It seemed like there was a miss, sounded awful. You should have seen my wife's face when I went back in the house. After about 10 seconds the idle changed in an instant and ran smooth; the RPMs ran up to around 1200ish (High idle?) …

Started off with finding out my heater core started to leak but the stuff should be at the house sometime within a week. But as of this morning I have know low beams but I do have high beams. So after worked stopped and picked up a new headlight switch from my local junkyard and that didn't fix it. I have checked the fuses and not really sure where to start next.

I cleaned my IAT Sensor this morning, wasn't that dirty, and plan on doing the MAP tomorrow morning (didn't have a 1 1/16 socket). This morning I checked the resistance on the IAT sensor, at approx. 43-47 degree F. I was getting 28.60 Ohms. Interpolating from Mopar1973Man's supplied temp/ohm chart, this sounds about correct. Anyone think that's incorrect?I also put a temporary air blocker in behind the grill this afternoon, as I noticed yesterday while driving to work 60 miles at a temp of around 27 F. that my IAT from my scan gauge was around 73 F. which seems a bit low. From the reading I've done here, the higher the better (up to a certain point I'm sure). Tonight went…

So earlier this week I put the big line kit on from my factory filter to the VP44. After checking all the connections I went to the car wash and powerwashed under the hood around the starter, whole factory fuel filter unit, and around the inlet for the VP44. This morning was 36 degrees and the truck started fine and drove about 30 miles on the freeway headed out deer hunting. Pulled up to my friends house and then the RPM gauge drops to zero, CEL on, and the truck started almost like hiccuping or bumping RPM up. Backed out and drove it down the street and the truck seemed to drive fine. Pulled over, shut it off, waited about a minute then turned it over. Tru…

well its been awhile since i have had to come on her fro help. but here i am. i noticed about a month ago my truck was idling a little high every now and then when i would have it in park. yesterday it got worse. i came to a stop on the off ramp and it liked loped. it went from 700 down to like 300 rpm a couple times at stop. i looked at my fuel pressure gauge and it was steady so it was getting fuel . i put it in N and it was idling at 900 to 1000. i drove to my bank and tried resetting my throttle by turning it the engine off and turning the key back on and pushing the gas peddle down slow and letting it back up slow. it didn't lope anymore but it was still idling at 10…

Ok so this problem just started but when I’m at about 55mph the rpms are usually 1800 but then they drop to about 1400 an jump right back in a spot second, no idea what’s going on

Hey all, I have a couple questions about shifting. My truck (maybe most vehicles? I've experienced this with other manual vehicles), is hard to get into 2nd when I'm rolling too fast, about 10-15 mph. Too fast to get into 2nd, too slow to use 3rd. Anyway, I recently finally discovered that if I bring the RPMs up, it will go in, not as nicely as normal, but a lot easier. Maybe I just need the RPMs higher still? Is this normal? Normal for a trans with 260k anyway lol. Also, when shifting, I have always gently released the skinny pedal while gently pressing in the clutch to avoid letting off the throttle too abruptly, and avoid the jolt you get if you press the clutch a…

Hey guys, I am just curious what's a safe RPM rage to drive these trucks on the freeway? I have a 4:10 ratio which I really want to change to 3:55 which brings me to another question anybody know where to get a good set of 3:55 gears? Regarding the RPM's I don't let it get passed 2 RPM's which with my ratio is 60 to 65 mph. So since I 'm new to the Diesel world what would be a safe operating RPM rage for these trucks? Just want to know what everyone thinks.

I'm wondering what speed people are going at what RPM. today i hauled a 35' 5er weighing in around 15000lb. and i was paying real close attention to my speed vs rpm.i didn't use OD while towing.2nd gear was 40 mph at 2700 rpm.3 locked was 55 at 2000. in od i turn about 1700 ish and go 67ish. i'm starting to think i don't have the 3.55 gear the sticker on the glove box says i do.thought and imput would be great.

Okay I have a 99 Cummins auto 4x4 with 199,000 on it and I just replaced the ecm and pcm and everything worked great till yesterday when I picked it up from having the u joints and axle seals done now it doesn't like to shift into that deep drone overdrive, if I accelerate lightly after 4th gear it will jump rpms then go into overdrive. It will sometimes jump rpms in other gears depending on what certain speed I am at. So what is the issue? I have heard alternator, tps sensor or crank sensor. This issue gets worse as I drive it to where it will jump in all gears no matter what speed till I pull over and poke around then it wont do it as bad for a little bit.

i've had my transmission rebuilt a month ago, new apps (timbo), cleaned and make sure i had good connection for my MAP and AIT sensor. No CEL. i've done the key trick and p1693 pops up so i hook up my scanner and i get no codes. i've put on all new HD battery cables and make sure all my grounds are good plus have done W-T's ground mod. i have no tuner. i have a FASS 150 and my fuel filters were changed a couple months ago and it has been the same before and after fuel filter changes. my truck drives fine from idle to about 2,000 rpms. when i stomp on it i've gotten it to maybe 2,200rpms but it feels and sounds like it's redlining or working really hard. now my abs and bra…

Hello again,I noticed the 2-3 inch rubber line from my hydroboost is starting to split. Is this high pressure hose or what is recommended to replace it? Thanks

Ever since I got the truck 3 years ago it’s always had a bad rumble while 4x4 was engaged. It hasn’t effected any performance of the 4x4 but it just doesn’t sound good. I believe it’s the double cardan in the front shaft but I’m unsure. It doesn’t seem to have a lot of play but I plan on removing the front shaft this weekend to see if the rumble goes away with 4x4 engaged to see if it’s the t-case or the shaft. I’ve heard that the from double cardan is a bear to replace but I’d much rather do it myself than spend $300 on a new shaft. Any tips to replacing this joint? I plan on doing all spicer joints so I hopefully won’t have to do this again for a while.

Driving yesterday,and layed it to the throttle(not any harder than i have before)now truck is running like crap. No codes,lot of white/light grey smoke from exhaust. Real rough idle,not any better above idle.:banghead:

so drivin down i25 @75mph with ac blowin cold outside temp 99F. temp gauge showed a bit higher than ive ever seen about 210. no problems, coolant is good never had a problem with overheating or over cooling till now. i wasnt hauling anything either. Now the issue i think is the tstat is stuck open allowing over cooling. barely will hit 170 in 99f heat with ac runnin doing 65. the fan is working fine, blowing strong but not locked. so i am gonna order a new 195f tstat and bolts then swap this week. thoughts?

http://mopar.mopar1973man.com/cummins/2ndgen24v/valve-adj/valve-adj.htm just got done running the valves.#6int and exhaust valves were out alittle.got them all adjusted in time before winter time gets here.:thumbup2:fired it up and the little tick tick was gone:thumbup2:

Hey guys, so since I've had my truck for a bit the engine temps are acting a bit weird. I know it's normal to climb up to around 200F before the thermostat opens, but mine seems to be doing it sporadically after the thermostat opens. For instance, driving home there was a bit of a grade for about a mile, and the temps climbed up to 208. The fan kicked on and it cooled back down. Then today, I was driving for 30 min or so and it was at 193, where it usually sits. Then out of the blue it climbed to 202 and sat there until the fan kicked on and it cooled back down. Ambient temps were both around 65*. I'm thinking thermostat, but it didn't do this before the new water pump.

Everything is hooked up on my Edge so far except the MAP sensor. Either I need to replace my stock one, or they gave me the wrong T harness. Either way, I'm not going to undo everything I just did if this is only going to affect the boost reading to the edge, or have no effect at all. So is ok to run my Edge with the factory MAP installed, or should I just not even bother hooking the Edge up to the battery until it's ready?

Ive been chasing down this problem for about 2 years and barely drive my truck because of the issue. So I have upgraded to the newest airdog II, new MWFI vp44, and 150 hp injectors, new head gasket, studs, and timbos apps. If you listen to my truck from about 100 feet away, you can hear it running strange but not picked up well on video. It sounds like a random ticking coming from engine like the cylinders aren't firing all the way or something but it is NOT a misfire (more of a random skip). This happens throughout all engine rpms. When im cruising going 55 and let off the gas SLIGHTLY (so little load on engine), the truck starts sputtering and can be noticed on tach (+/…
