Engine/Transmission (1998.5 - 2002) Update on the truck Dying.

[Agades]

that is very possible



ive had two flashes done now

I wonder when the ecm will just crap out

 

[ToolManTimTaylor]

Kinda like writing to an old floppy disk ... its good for just sooo many write to's

Don't feel alone... I am and have been in the same boat for about two years. I have changed tested every electrical connection and sensor on the truck and still have the problem. I have a new ecm and VP44. That helped for about 8 months and gradually started with the studder bucking under light acceleration with small and heavy loads. And to think that I had a 98 12v quad cab ordered and canceled for the new improved 24v. Boy am I kicking myself!!!

 

[Agades]

makes a person really sick to think about how much money you spend to have the perfect truck only to be wrecked by a computer



I got a price on trading to an 03 this morning



NOT PRETTY



my truck is only a year old and 27000 miles

what do ya think it should be worth???



im starting to lean towards a mechanical conversion again

it would be cheaper

Mine stumbles most when its cold, if you take off about 2nd gear she just holds one rpm, no matter if you floor or pump it. A few seconds later the thing takes off. Also, when in neutral or park, rev it to about 1800 and tons of blue smoke with stumble. Somestimes higher roms. Then the next time it wont. The problem is that the problems just never keep repeating themselfs.

Computers --tdr article

The reason I posted before was just to point out what the tdr article was saying about computers and reflash. The article was referring to hunting and constant back and forth shifting in and out of overdrive. It basically said that on earlier trucks a sensor or bad sensor was usually the cause. the newer the truck ,the more likely a computer reflash was necessary and the more likely special service tools would need to be used to diagnose the problem --in other words the dealer service dept. I , like you, want to keep my truck away from the dealer because some of them will do reflashes whether you want them or not. The issue of the oil pressure warning being defeated comes to mind.

My home computer got ''reflashed '' by installing a printer. the software to install this printer so corrupted this computer that ,the printer or no other printer could be installed. We had the whole memory erased,re-installed windows 98 ,and the printer still could not be installed. Every other function of the computer works fine. I have to wonder about all the electronic noise that these fueling boxes generate and what effect it has on the factory settings -- especially if the connections vibrate loose .

The only bomb i will consider for now is 275's . If my truck does not work, I can't work either. I would like to buy an older one-- maybe a 12 valve -- and bombs away.

good luck TMTT

I seriously hope you can come up with something



I have failed to get any where with this

[daveshoe]

[2-ND TIME]

engine bucking

Sorry guys Iam very tired but do you know one of the sites that have the print out of the injector pump where it shows the electrical of the vp-44 I belive that the pump is getting a varied signal form the ECM/PCM APP's that not holding the fuel advancemnt solonid open??? Can any one read Polish and interperate what is on the one website please??? Must go sorry too tired. 99 1ton 5spd 4x4 with engine stumble since new.

If it's in text form go to www.Freetranslation.com Cut and paste and translate it?



As for me ... The date of my last post I had cleaned up the battery connections. Can you believe th etruck has not given one Iota of a problem yet!? Hmmm we'll see.

 

[Agades]

I cured mine by getting an 03

I love it

its great

gonna miss the old one but then again I wont

 

[Agades]

tool man,

just wondering

did you come up with anything yet????????

 

[pro99]

Working at the DLR we found that the second battery was not conducting to the drivers side battery. You could check for continuity from the battery post and the bolt that runs threw it and nothing. This is the the battery post on the drivers side. The bolt was not making a good connection. It would cause tons of concerns with diesel trucks Like spikes in the system , OD going in and out, surges and tons of other things. Like you said clean battery post and concerns are gone. The smallest things could fix big concerns... ... ... ... ...

Yep all is well with the truck!



WHEW! Saved some BIG Dollars!



I found that:



1: The factory mopar battery cables have alot left to be desired. The cable connectors for the battery posts cannot make complete contact with the post thus alowing a thin coating of corrosion on the cable connector between IT and the POST itself. I re ground the cable connector and post with a 2. 00 terminal cleaner / reamer and put her back together. The truck has been perfect ever scince!



2: The main ground:

The flat washer that conects the cable to the engine block is of the concave type with a zinc coating. I took a standard grinder and ground an orbital pattern on the surface of the washer to flatten it a bit and sanded the block. THIS ALONE was a major issue. After re attatchment I coated it with protectant.

Idea...

Hey TMTT your truck still fine?



Got an idea here... .

IF the stumble-miss-hesitation whatever we want to call it is software related, well then.....



You'd need a reflash. Rigth?

Hehmmm, dunno how to say you this guys.

Get the Superchips toy and reflash your truck on your own.



IF that solves your problem, fine you've got a new toy and maybe a little more power.



If not, well 30 days money back.....

Marco,



What do you reflash with? Does the superchips program help with the stumble? I heard the superchips flash did not add much power.



Thanks in advance,

Charles



BTW, how is the Mad Marco ECM coming?

 

[Marco]

The idea behind my thinking goes like this.



I've personally seen original softwares ( 3 of them ) from DC that made my truck stumble like many on this board describe. The cause was/is the fuelling table. Once that is corrected no more stumble...



Let's assume we have members here that have those softwares in their ECM. They will need a different fuelling table to get rid of their problem.



Here comes the Superchips toy into the game. It has a fuelling table that does not stumble. Better they have 4 different fuelling tables. Stock, level 1-2-3.



If that still doesn't fix the problem, you've ruled out the ECM as a possible cause and best of all, 30 days money back... .
