2001 Dodge Ram 2500 Q&A
2001 Dodge Ram 2500 Question: Throttle quits responding while driving?!?!
Diesel specialist needed. Hello guys, I'm new to the site. Been searching on here forever for an answer to my trucks lttle problem,....but I did not succeed to find one. Sooo i signed up,...and here is my question. Let me introduce my truck first,...so that you all know a bit more then just the bare basic it being a diesel. My truck is a 2002 Dodge Ram 2500 quad cab SLT 2x4 Laramie '94 to '01 model with 115K on it. With a Cummins 5.9L 24Valve 6 cylinder Diesel Engine Replaced/serviced parts: -Airconditioning freon powerups every year. -Calipers, rotors and brakes replaced all around at 100K. -Oil changes: every 5K with LUCAS oil additives all around. -LUCAS additive oils in : Engine, Transmission, Fuel tank, and all grease fittings -Batteries: two Optima red tops since 2008 -Fueling up eveytime there is only a quart tank left,...I NEVER let the fuel gauge get too or near the RED line! -K&N lifetime airfilter added at 108K part#33-2056 Price: $82.99 Engine start: no problem Engine idle: no problem Engine idle with A/C: no problem Engine reving cold: no problem Engine reving warm: no problem Pull power degreased a little bit after adding 20" wheels with Toyo 33x12.50R20 LT Open Country tires without any transmission changes. Transmission is a standard automatic. My guess is that I should of done something to the transmission to have the same pull power,....or maybe there is something else going on,...i really dont know?!?!? Anyway: Driving - cold: throttle respons is bad, then a few seconds later its OK,.... then no matter what speed I'm driving the throttle is all of a sudden not responding any more. It feels like my throttle is freezing up,....NOT litterally ofcourse,.....the foot-pedal pumping action works throughout this "freezeup" session. Then it takes about 30 seconds to a minute too respond (while slowing you down 10-20miles per hour) and then finally speedup again. What does that throttle behavior mean? -Fuel filter needs replacing? -Bad fuel pump? -Injectors gone bad? Please HELP. Any advice will be greatly appreciated. Thanks in advance.

You need to replace the throttle position sensor (apps) and I've replaced it 3 times on my 1998 Ram Diesel (260,000 miles) and you can get one here for half of what dodge wants http://forum.mopar1973man.com/showthread.php/772-Timbo-APPS Got mine in a few days and had my diesel mechanic install and runs great actually runs better than the dodge sensor. - hemicuda
