Driving home for the holidays, going about 60, my RX350 vibrated a bit and the check engine and VSC lights came on. From that point forward, I would experience vibration at 70mph or so. Ran it in 4th gear and things seemed to smooth out a bit.
Ran it over to AutoZone this morning to see what the codes read. Here is the list; in order
PO301- C1 misfire
PO300- random misfire
PO302- C2 misfire
PO303- C3 misfire
PO304- C4 misfire
PO305- C5 misfire
PO306- C6 misfire
PO354- Ignition coil D primary/secondary unit
PO301- C1 misfire
PO300- random misfire
PO302- C2 misfire
PO303- C3 misfire
PO304- C4 misfire
PO305- C5 misfire
PO306- C6 misfire
They suggest replacing ALL ignition coils and spark plugs. They are $100 a piece or $370 for all 6. What do you guys suggest? I cant imagine that all of them need to be replaced or that this could even be the issue.
