Attention: TDR Forum Junkies I've just picked up a '02 3500 24V with a couple of irritating problems.
First the injection pump was bad and i had it replaced by Dodge under waranty. However it is still pouring out diesel smog anywhere past 1/4 throttle unless the turbine is spinning at full speed. What it looks like is that i have the system programed to dump as much fuel in as possible at all times. I think that when i bought it, someone had cranked up the fueling and had not turned it down when they sold the truck.
The Dodge dealer claims that they can't put the "original" program into the truck.
However when i used the smarty we have for another truck to push the programing down to level 0, no smoke at all and it now drives like my old 2006 third gen 2500.
Anybody got a good idea what i can say to the dealer to get them to reprogram the system with the true default program??
Second problem is a bouncy cruise control.
I thought this might have been originally related to the injection pump but it is still with me after the pump was replaced.
what i see is the cruise engages and then the rpm bounces up and down just about 50 to 100 rpm. The speed changes about 1/2 to 1 mph rather jerkily. It is progressively worse depending on what speed you want to hold. At 50 mph you don't see or feel it really. At 70 it will drive you nuts and make you not want to use the cruise. Steeper hills will make the problem much worse. It's like the computer s getting incorrect speed sensor data.
I'm not really sure where to look for this problem.
Anyone got ideas?? Love to hear them.
thx

I thought the 02 H. O. used vacuum also. I have an 01 manual but not the 02 so I am rather curious.
