01 24 Valve losing power at highway speeds

Alright folks, sorry if this is a repost. I have a 2001 Ram 2500 5 speed 24 valve with a Bully dog Torque dog chip and stage 2 injectors. I notice that when i'm driving at normal speeds, sometimes the truck will just stop accellerating. I can gear down and sometimes it will gain power and sometimes it wont. I've also noticed that it happens more at night. I guess because the temperature change?? I will go ahead and say that I do not have an aftermarket air filter, but it done this before I bought the chip. However, the air filter in the truck is in dire need of attention (cleaning). I don't know if this will help, but i'll find out tomorrow. The injectors and fuel pump are brand new, so if its not the air filter, then i assume its going to be the injection pump? If so, would it not be cheaper to get the air dog system from pensacola diesel for 599 rather than dropping 1200 dollars for a new factory one? Any help will be GREATLY appreciated.

If the truck is fine at slow to medium speeds, or pulling for that matter, then the injection pump should be fine.  This sounds like a typical fuel starvation issue, and the weak link in all Dodge Ram trucks with the Cummins is the lift pump.  If you can check the LP fuel pressure, it should be no less than 12 PSI at wide open throttle.

There are holiday prices for the AirDog, and I've seen it as low as $499.

Do some more troubleshooting and let us know.  We're more than happy to help.

I bought a K&N recharge kit and cleaned the air filter and drained the water out of the fuel and it seems to be doing a lot better. I'll find out more as the temperature drops and let you know.

Thanks,

Are you throwing any codes?  Not accelerating can happen with a bad IP or fuel starvation...  Which will also cause a bad IP.

Let us know what codes you are throwing if any.  Based on this, we can all help more.

Lose the K&N, they are horrible for diesels.

There are a ton of better choices out there, and you don't need that red oil on your turbo fins collecting dust.

No, I'm not throwing any codes. The K&N is what came stock with the truck. It is doing a lot better. Now it only does it if I don't let it warm up and only then for about 5 minutes. As far as highway speeds it runs like a sewing machine. I also drained it seemed like a gallon of water out of the fuel filter, but the thing was my water in fuel light never came on?

Whats wrong with the k&n? they keep all the dirt out plus flow better so you can hear your turbo.

Hello,  I just purchased a Ram 2500 with 24v Cummins.  I noticed an occasional dead pedal effect when driving on inclines.  The truck is a 2001 with 194K miles.  Any advise on what may be causing this or what i should do to determine what to do next would be greatly appreciated.

Thanks.

Mike, I don't know how bad yours is, but mine turned out to be water in the fuel. If its not throwing any codes, I would drain the filter housing, replace the fuel filter and add 2 16oz bottles of sea foam to the tank everytime you fill up. Do this about 3-4 times depending on how bad it is and you should notice an improvement.

Mike,

The dead petal is going to be either the APPS or TPS and can be fixed in an afternoon, but you'll need to figure out which is causing your problem.

Do NOT use Seafoam.  That stuff will ruin a good engine.  I suggest FPPF to remove water, and Power Service as a cetane booster and injector cleaner.

I've ran seafoam in my truck and it hasn't ruined anything. A lot of people use it in their trucks/ tractors. As long as you put the correct amount you're not going to hurt anything.

When your truck stops accellerating, does it just not pick up any speed? Or does it just seem to drop to an idle? If it drops to an idle, and it seems to happen more at night when it's cooler and the air has more moisture in it, I would suspect the throttle position sensor. Keep that air filter clean - can't stress that enough. A clean filter means more air, = more power, = cooler temps. The k&n is a good filter - I've had one on my '01 dodge since the beginning, and I now have over 450000 miles on it - but I clean it every oil change, the k&n cleaning kits are not very expensive. Seafoam is great for cleaning out a dirty fuel system too - really clears the water out. I use it every time I run into poor fuel.

I've heard more bad than good about Seafoam, and obviously there is alot of folks out there that don't like it.

I stick with what I know works and have used FPPF for a long time (since 1987 at least) and I don't have to worry about it being mixed right.  Dump a bottle in, fuel it up, and go.

What is FPPF? And where can I get it? I may try it. BTW, I figured out what was wrong with the truck and it was the bully dog chip. It runs like a sewing machine now. I do not have a cold air intake... could this be the reason? Confused
