How do i make my mopar a daily driver??

I agree; EFI cars are not bullet-proof, and when certain parts fail or work intermittently, you can pour a lotta money into diagnostics. If you don't understand the EFI system, you can be at the mercy of your dealer, or mechanic.
By contrast, carbs are pretty simple and robust.They may not be perfect..... but almost anybody can master the one under at least one hood. Or at least understand it well enough to keep it running.
