    I also took ohm readings of my current injectors. They vary from 12.9 ohm to 13.8 ohm. Is this ok?

    Hey sorry for the late reply. I’ve been busy with work and haven’t had much time to check it out. I checked the voltage going to the sensor, it’s 5 volts. At key on engine off the sensor signal is 4.5 volts. At idle the signal is 1.7 v. How does this sound?

    Hey Fast69Mopar. I went ahead and bought that specific map sensor at oreilly's. However the readings were the same. It might be my scanner that reads these values. Thanks for the idea though.

    Is there any information I can learn from this? Thank you.

    This is the screen with key on engine off, on my code reader scanner.

    At Key on Engine Off the map sensor signal is 30 inHg. At idle it is 12inHg. I will upload a video of this. Is this maybe a bad or wrong sensor?

    I thought I read somewhere that the MAP reading was only the difference between atmospheric pressure and the gauge pressure. If so then that means my MAP sensor reading is within working conditions? Or is this completely wrong?

    As far a vacuum leaks, I performed a smoke test similar to this one . I didn't find any smoke leaking out any where. The MAP presure was set at 11 inHg and gauge read 19 inHg. I read that this was a good reading to have since the MAP reading is the atmospheric pressure (around 29 inHg) minus the...

    I got a 2004 Dodge Ram Hemi 5.7 from my brother. It has 250k miles on it. He said the motor had been rebuilt but it still wasn't running. I fixed a few bad sensor codes. I decided to change the fuel injectors on it with some OEM ebay ones. Now that I think back on it I shouldn't have done this...
