Hi scotty,
I recently bought a 2007 dodge charger rt for around 2400$ and have 2 issues :
1. The fuel gauge some times indicates lower than actual and then adjust it self within few minutes. I changed the second fuel pump but the issue still happens.
2. While cruising at 20+mph (car goes into eco mode ,4 cylinder) i can feel vibrations and higher engine noise, when i shift to manual it all goes away.
Finally if you have any tips to prolong the cars life
Note : The car throws error codes p0430 ,p0420 and p0645
I would try to disconnect the Eco mode crap there are people have kits that do that. And you probably need a new fuel sending unit in the gas tank
Thanks scotty, will try disconnect the mds, and I will check for the sending units
My regards from bahrain 🇧🇭
