Injector Open Circuit - Cyl 5, CEL?
Any idea if this is anything serious? I cleared the codes with the engine running and with the car off, but all three came back immediately (the other two are old ones related to the "heating element" of one of my O2 sensors?). I probably should have written the actual code #'s down...
Either way, the car isn't suffering from any symptoms that I can discern, past being a tiny bit sluggish in the low RPMs (long past the time for a Jerrytune, methinks!), although the idle does get kinda "lumpy" sometimes after I've driven it hard and then come back to an idle. *zero* backfires or hesitation or anything like that though. Still getting great MPGs when I'm not lead-footing it around, too.
Just over 70k the other night and the plugs/wires are still stock, AFAIK, along with the fuel filter. New radiator/coolant, Green filters and recent Mobil 1 Syn 0w40 oil... Could it just need a tune-up, basically? I reset the adaptive driving thing pretty much every week, and it still comes back just as "fresh" and responsive after a reset as ever, especially with the cold weather that's been sneaking around recently.
Any ideas before I take it in to the stealership are much appreciated, so I don't get taken for a $50-$100 "diagnostic" fee, for them to find nothing...
