I posted this over on the newbie check-in and realized I should be here.
Any thoughts on what could be causing my truck to be sluggish at low rpm/part throttle? (2003 Ram 2500 4x4 CCLB)
Ive been working on my truck
t try and solve the poor throttle response issue. New balanced injectors, new fuel rail, new fuel pump assembly all installed now.
No difference in performance. Has very decent power over 4000rpm @ wot but just seems really sluggish at tip-in and part throttle driving...which is where I always drive it. Also my ,ileage is poor in comparison to other owners on here. Im getting around 10mpg driving carefully at the rural speed limit (50mph/80kph). I was beginning to think the poor low rpm torque is normal for a gas truck of this size....until I took my camper to town for servicing this afternoon. It is 30 feet long and has the ford v10 rated at 365 hp and it is far more responsive then my much lighter ram truck ??
Can anyone speculate as to what it culd be that is holding this truck back? Perhaps the fly by wire throttle? As I side note I had a hemi powered durango back in 04 and I recall it was quite peppy. It must have had the same throttle system?
Also, I did the tmr delete and it helped make the shift less mushy at high throttle openings. I did the throttle reset procedure as well.
My tps reading is 14.5% at idle and 84% at wot. Should it read 100% at full throttle?
No codes at all. I have a trinity and tried several different tunes, and the only noticiable difference was at wot and high rpm. Also it started to ping even though I have been running premium for 3 tanks now..
I dont want t give up on this truck since I just decided that 60,000 was just crazy for a new diesel ! I felt great about saving 50,000 and driving a really decent truck but I am at a loss as to why it is so sluggish?
Any thoughts or experience with symptoms like this?
