Hi Everyone. If any one has a Chrysler/Jeep/Dodge/Ram with the 5.7 Hemi V8 and is having acceleration, rpm, or other problems, please read. My dad has a 2006 Dodge Ram 1500 V8 Hemi 4X4 with just over 148,500 Miles. When in park or N, if you pushed the accelerator just a tiny bit and held it (like trying to keep the rpm at about 1,000 RPM), the rpms would rev up and down. When driving at speeds 40 + MPH, when letting off the accelerator and then putting it on again, the transmission would shift out of overdrive and then back. It would do the same when using cruse control. To accelerate from a hill, you would have to press the accelerator a little bit less then 1/2 way down. The last problem, when trying to accelerate to pass someone, the accelerator would be floored and you would have to wait a good 5 + seconds before the transmission and engine would react. So our mechanic replaced sparkplugs and other components. But that did not fix the problem. So My dad and I have been driving it that way for years. Today, we decided to replace the throttle body (because the Throttle Position Sensor "TPS" is built into the Throttle Body on the 5.7 Hemi and has to replaced as a whole unit). I did not think this would make any difference. I was completely wrong. It really woke up this 5.7 V8. The engine had way more power. Your punch it and immediately it accelerates. Then I took it onto a 45-50 MPH road to see if it stayed in overdrive like its suppose to. It has enough power now to pass people. No waiting for it to react. The only problem I have now with it is just getting use to how sensitive the throttle is. You just touch it and it was to get up and go. Now I can keep the RPM exactly where I want it which helps when trying to jumpstart people's cars. So if you have any problems like these, try replacing the TPS & / or the throttle body. If any one is wondering where I got this part, I got it at my local O'reilly Auto Parts -
