Stories are circulating about fuel injector failures on the FA20 engine and we just pick up this following technical document by Toyota USA, from ft86club.com, explaining the problems (misfiring, pinking sounds, leaks) and other strange behavior some of the FA20 power plants are exhibiting, along with what seems like a software remedy.
You can also check the main thread from which the below document was picked from, thanks to YoungJae for sharing. Just be aware there seems to be a decent dose of information and ‘mis-information’ regarding the problem as its all over the net.
