Christmas Eve and Santa gave me an engine warning light. I used my generic code reader and produced a P1316. Further research on mfr's detailed code on the Internet said I had a problems with my #6 fuel injector. Please share with me your wisdom on next steps. Should I turn off the light and assume it was an intermittent event? Should I go about replacing the injector? Is the use of an injector cleaner recommended? About a month ago, I used a can of Sea Foam. Could that of dislodged some material? I have always found salvation on this site. By the way, I know this can be a serious problem because several years ago I bought and repaired a 300ZX that had an engine fire caused by a faulty fuel injector.
