Hey guys,
I've had my 05 Ram for over a year now and it's been working great, however I have noticed today and on rare occasions it has a tendency to "pulsate" at low RPM's, when driving, the RPM gauge (usually around 1500-2000 RPM) will pulsate or fluctuate between 2-300 RPM. If I start the truck up cold and slightly tap my gas it will sometimes pulsate as well. ( sounds like a heavy cammed engine?) It also had a slight "lag" or delay at a dead stop to acceleration, Not a slip, just a delay like the RPM gauge pulsated before winding out, but not every time.
No high RPM's with no movement the truck still has its get up and go for certain. Doesn't rev up at low RPM, and at high RPM it still has the pull if I hit the peddle for more acceleration.
- I only used ATF4 Mopar fluid, recently changed 10,000KMS ago.
- Only use Full Synthetic Castrol Edge
- Currently running 89' Octane fuel
- I am in my winter season usually -10c to -20c if this makes a difference
- Throwing codes " P0440 P0441 P0406"
- I sometimes like to put the truck into 2nd on slow roads, for the sound (Haha) if this would make a difference as well.
Any ideas on what could be going on?
