Diesel specialist needed.
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
-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?!?!?
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?
Any advice will be greatly appreciated.
Thanks in advance.
