Engine/Transmission (1998.5 - 2002) New to TDR and Needing Help

[AutomationJoe]

Hey Guys!

I'm a new member of the TDR and am a recent convert to Diesel.

I have a 2002 Ram 2500 4X2 SWB, Nerf Bars, Rhino Bed Liner and about 60K of Highway miles behind me.

I love my Diesel and couldn't imagine ever owning anything else.

However:

I am having a throttle response problem that seems to come and go as it pleases. The tech at the Local Dealer is stumped. They've had my truck for 2 days and they still can't find the problem. :{



I was hoping that someone else might have had a similiar problem and had some insight into what was going own.



I can be driving my truck for about an hour and then I can feel the truck begin to lose power. I can mash the pedal to the floor and the truck will not respond. No acceleration, nothing. It's like the exhaust is closed tight or the engine is starving for fuel. I can maintain close to my current speed when this happens, but I cannot accelerate.



If I drop my RPM's or down shift, the truck will start to accelerate again, but I may go through this cycle over and over again until I let the truck rest a while.



I've changed my fuel filter and I have had the Dealer's tech check the fuel pressure from the TPS and the VP44. The service tech told me that my fuel pressure is good and they are not sure why the truck loses throttle response.



My hope is that someone with the TDR has a better knowledge of such problems with the 24V ISB and can lead me to a resolution.



Thanks for the Input

Have the dealer check your throttle position sensor located above your injection pump. Mine did the same thing and set a code. If you cycle your key on and off three times leaving it on the third time any stored codes will show up on your odometer. Then check the code nubers in the 911 archive section.

Thanks For the information Black-Smoker!

I'm picking my truck up in the morning. The dealer said his tech will be out till Tuesday and I would have to wait until then for them to continue trying to diagnois the problem.

I'll check the codes then.

Thanks Again!!
