I have a very strange acceleration problem on my 1995 v10 4x4 ram. Many times it feels like I'm only getting 25-75% of power/acceleration I should be feeling when stepping on the gas, only at very low speeds. It seems to happen most after I've been parked on an uphill incline, or if I try to accelerate from a stop where i haven't let my truck come to a complete, semi-abrupt, stop. It does also happen, just not as much, from a complete stop on flat ground. Basically, I can lightly accelerate, 2200 rpm range, and have very little speed increase, then after a few seconds the truck decides to acknowledge the fact that the engine is working, and then it takes off with the 'normal' (it has 120k miles) acceleration that it should.

What should I tell a mechanic to look at, my tranny/differential/something-else?

 

i had a fowled plug that caused a similar issue with mine, do you have a CEL?

 

Tell him to look at your truck! If you're going to pay a professional to apply his knowledge to your problem, just let him do his job.

I cannot describe just how insulting it is to a professional to be told what to do by someone who knows a lot more than he ever bothered to actually learn. It's so insulting that many, myself included, will let those people spend all of their money without ever addressing the problem -- you want this done? Okay. Now that? Okay. No problem. Oh, now you just want your problem solved? Why didn't you say so in the first place?

Good luck with it!

 

Tell the mechanic what the problem is. Let him take it from there. That IS his job after all. Unregistered is quite correct.

 

Several mechanics have looked at it in the past years, with zero results. I'm hoping someone here has had a similar problem, or a clue to what it may be, so that I can take it to somewhere local that specializes in, or is well reviewed for, that particular problem.

I've tried taking it to people, asking them to fix it, for a long while now. No mechanic yet has touched the problem, though they don't mind charging me for things that they say could work, yet never do.


Nope, no check engine light

 

Have you been to the dealer?

If you have the ability to do data logging, (which is probably the only way you are actually going to be able to figger this one out.) keep logs for a while, and when the problem presents itself, compare "bad" logs, to "good" ones. See what differences there are, and take it from there.

Not gonna be an easy fix. Well, it might be an easy fix, once you know what you NEED to fix...... figgering it out is just gonna be fun.

 

Bad plugs
Wrong plugs
Bad plug wire, ie: broken and making poor contact
Plugged or collapsed Cats
It's a crap shoot, I've had all of the above affect my truck and it's accelleration.
The last one came with what is known as PING under hard accelleration.

Also the early V10's were prone to the heads cracking.

Not saying that any of these are you're issue, just some simple things to check.
But as Hey you said a dealer is probably you're best bet.

 

Sorry to bump such an ancient thread, but I was wondering if anybody ever found an answer to the problem? My husband is having the same issue with his '01 2500 5.9

 

The original poster hasn't been back since december last year.... so, if he did get it fixed, doesn't appear he is going to be telling us about it.

Have your husband check his plenum. (stickied thread at top of this forum, with all the gory details. )

 

Nobody that I've taken it to (dealer, multiple mechanics) can figure it out.
