The Under the Hood
Show
Dear Motor Medics, My 2006 Ram 1500 truck is having problems while accelerating. The engine power is low when the RPM gets over 4,000 RPM but is fine at a steady speed or when under 4,500 RPM.
My husband and I have spent a lot of time looking on YouTube, including your channel checking for easier things that we can do. We found out that it did not have a fuel filter and we have bought a good Autel scanner so we can read codes, but there are no codes in the system.
This problem came on gradually over about 5k miles and seems to be getting worse. There is only slight noise, we think is coming from the drivers’ side valve cover near the front.
Should we pull the cover? If we do, what are we looking for?
Thank you, Everly in Yakima, Washington
Dear Everly, Most people would not go as far as you have before reaching out to a repair shop.
These Rams have had some cam issues we have seen in our shop. They tend to make some noise at first, which gets louder and increases as does the power loss.
Pull that valve cover and look at all the rockers while you turn the engine over. If one or more doesn’t move as much as the others there is wear present. This will cause a lack of cylinder filling and low power at higher RPM.
Next, look at the cam and lifters and rockers for wear and consult a shop for the next step.
Take care, The Motor Medics
