2002 Dodge Ram 2500 Q&A
2002 Dodge Ram 2500 Question: Why would I get no quick responds to pushing on the "gas" pedal.
After driving on highway approx. a hour my diesel sometimes does not respond to me pushing on the pedal. If I let up and push again it responds. Always after highway driving and has only just started this. Not everytime I drive it. OEM lift pump, everything. Could I have a pump going bad. Just ordered a performance pump. only have 60000 miles on truck. Sat for long time but have put thousands of miles on in last few months. - Budwin
Have the fuel filter replaced just in case you have recently gotten some contaminated fuel. The main issue your having is very likely the throttle position sensor which are problematic on many Dodge truck models as well as the TPS wiring connector. If the TPS is the issue, it can be replaced or a shop can install a resistor in the wiring to the ECM to fix it. Also have the computer scanned for problem codes which might shed more light on the issue. The following link is to geno's garage with a better description of the TPS issue. http://www.genosgarage.com/AFTERMARKET-APPS-THROTTLE-POSITION-SENSOR-985-04/productinfo/TPS98502/#.U4OQwvldWrk - lightsaber
