So my 97 1fzfe 80 Recently started to have an incredibly small misfire/ hiccup , almost feels like an injector has a small hiccup, does not affect performance in any way at all, and honestly nobody would feel it unless pointed out by me . Nothing shows on tach , but if you sit and hear it long enough you will feel a very small “almost misfire” my scan gauge will flash 2 store codes very quickly then will show zero stored codes ? I was told they’re soft codes , where the computer picks up something but not enough to trip a code.. the 80 has brand new OEM plugs wires and dizzy cap, the only thing I can think of is an injector starting to show signs of it getting weak, I’ve ran fuel injector cleaner , fuel system cleaner etc.. was going to try a higher octane fuel, then perhaps check the wiring harness , but it’s been wrapped and no matter which why I tug it I can’t make it worse … anyone ever had this issue ? Or should I just drive til it gets worse ? Cause as of now it’s extremely difficult to recreate or show anyone …
