Today something unexpected happened. I had a birthday party planned this Sunday, the place is 45 minutes from my house. Before the party, I went to Home Depot to return a rented equipment and didn’t noticed any misfire. During the 45 minutes trip, no misfire felt. After birthday party, when I was driving back home the check lights at panel spontaneously turned off! The car is driving smoothly again.
A day before, I filled up my tank at a different gas station (and put premium gas). I don’t know if if have something related, but probably had something at fuel injector causing the issue (??) and the different fuel clean it (??).
I planned swing by Toyota dealer tomorrow afternoon to buy a new replacement coil, but now I will wait a little bit more.
By the way, have any of you ever used those high mileage fuel treatments ?
Worth it? Helps clean injectors? Or the risk to damage something don’t make sense?
