hello,

To deal with a code 0300, 4 spark plugs and 4 coils were replaced originally. But right after I replaced the 4 fuel injectors, a new problem arose and it would crank for 2 or 3 seconds when starting, however there's no problem when I restart within a couple of minutes. Now it occasionally reads check engine code 172 and 300. The problem persists after replacing fuel pressure regulator and MAF sensor. Is it possibly a leaked injector? (the battery is okay)

OBD data (idle)
Long term trim -28.9
Short term trim -10.4
MAF 3.43
ETC 75
IAT(C) 31



Please help.
Thanks!


I didn't find the right solution from the Internet.

Hi, I don't think that someone in the forum deal with this things, maybe Mirko the programmer of Ecubike knows about this kind of errors codes...However from the symptoms that You describe I believe that your diagnosis it is correct(in part), I will explain myself better, the problem could come from the injection system, how many miles do You have?Did You clean up the throttle bodies?If You didn't clean up and You have a lot of miles, maybe can be the answer, if You did, maybe during the cleaning something went wrong, a small piece of paper remaining somewhere inside or some residual remaining inside somehow....
Now let me know something, how can be that Your FZ/MT 09 have 4 coils and 4 spark plugs? Since it is a 3 cylinders, suppose to have 3 coils and 3 spark plugs :wtf: :wtf: :wtf: :wtf: Maybe the problem is there, too many coils and too many spark plugs :lol: :lol: :lol: :lol:
