Hello for some context I have a 2005 Chrysler 300c rwd with about 180k miles and I saw it had an extended warranty of x53 and took it to get the free gas tank because I couldn’t fill the car up without it stalling on me. So they diagnose it and say it’s bad gas and that they have to drain the gas and clear it. So they do that and give us a call back and say the cars is running on 4 out of the 8 cylinders but when I took it to them with the “bad gas” in the tank it ran great with no misfire.
Could anyone help me understand what could be wrong with my car?
