Re: 2005 Expedition Hard Start and Rough Idle
Chances are your powertrain warranty is up. I'd also assume that if your problem is sensor related (IAC/TPS/EGR/MAF) then the powertrain warranty wouldn't cover those components. EGR and MAF should be covered under emissions warranty, if I'm not mistaken. I'd replace the idle air control sensor around the throttle body for around $40-50 depending on where you can find it. It only takes 10min or so to install with basic hand tools. It may not hurt to get the vehicle scanned for any saved codes even if the engine light isn't on
