2000 ram 1500 not accelerating

Scott5.2 · May 24, 2016

I have a 2000 Dodge Ram 1500 5.2 liter that won't accelerate properly. I have already replaced the catalytic converter thinking it was clogged but it's still accelerating improperly. Need suggestions on what it could be. I also have done a full tune up and changed air filter and spark plugs and everything.

Need more info. Plenum done? Any misfires? Did you just buy it? Etc.

We need more to go off than "its slow" lol

Scott5.2 · May 24, 2016

I gotcha have not done the plenum but i know i need too and have had it for almost 3 years i dont think its misfiring. It ran fine one day then the next it didnt. Thats all i know really

Any codes showing up?

Could be:
bad O2
throttle position sensor
crank sensor

Does it rev up when you press the gas pedal?
Do you feel anything? Could be bad fueling.

Need some more info or a video

Scott5.2 · May 24, 2016

Not throwing any codes except for when i removed the tps. Revs up fine and idles fine just when u get going down the road it acclerates extremely slow, lack of power does not feel like its skipping a beat.

Hows the plenum? Edit...Just read you haven't done it. If it's not throwing any codes have you checked the fuel filter? Does it shift properly?

Scott5.2 · May 24, 2016

It shifts properly and have not checked fuel filter yet because of having to lower the tank but will try to check once i dont have as much gas in it.

Shine a flash light down into TB and see what she looks like! If there isn't any codes I'm at a loss and you'll have to wait for other members.

Rev it in park up to 4000 rpm.

If it reaches it, that will tell you if the cat is clogged.

Cats been replaced.

I'd simply start with the plenum and possibly comp test. Or live in ignorance like myself there

Doesn't mean it isn't contaminated already.

Touchè. I did assume lol

Scott5.2 · May 25, 2016

Its not the cat i just got it back yesterday from getting a new one installed, on the way home it did the same thing its been doing no differnt.

Check compression and fuel pressure. If you've got access to the tools, it's very easy on these engines and the info gained is invaluable.

Scott5.2 · May 27, 2016

Update on truck is that everything is Firing fine and fuel pressure is good plus exhaust has been ran through and no clogs. Still not getting prper power. Any more ideas?

How much oil are you going through on a weekly basis? I was losing half a quart a week when my intake plenum gasket was blown.

mario.macias575 · May 28, 2016

I was using about the same amount of oil.

If im going to replace the crank shaft, does that mean that my timeing belt went of a few sec

This. We need to find out if your plenum is bad! Wonder if you could try letting computer reset and drive it around hard?

Edit: mario.macias575 I think Yeret is talking to the OP Scott. For you I'd suggest getting a 360 or another truck depending on how long your oil pump was going bad. Or be cheap and get another 318

Edit: Scott do you think we could get a video of this slow acceleration lol. I'm leaning towards blown plenum. What kind of plugs/wires did you install?
