Engine missing

[04nick]

I have a 04 Ram 1500 2wd with 120,*** miles on the engine, when I'm doing around 55-60 MPH going up a slight grade at around 1600-1700RPM the engine feels like it starts missing. I have thrown no codes and am curious if anybody else has had this problem, and where to start looking. hopefully stay out of the dealership.

I think a Hemi...its in his profile to the left.

I would start with replacing the 16 spark plugs(if they haven't been replaced yet. then i would replace the PCV valve and clean the throttle body for coking on the butterfly. that would cause a lot of the stalling and rough idle.

It is the 5.7 Hemi, thank you for the info. how would i go about cleaning the throttle body?

the easiest way to do it would be to remove the TB from the intake. and bench clean it with brake clean or throttle body cleaner.

Did you come up with a solution? I'm having the same problem...

DO NOT USE TB CLEANER! You take a chance of damaging the sensor.
