sup, so I took my 89 s13, stock sohc ka to my buddy who is a nissan tech so he can check what triggered my check enging light.
Well he printed out the code it read code 45 leaky injector. Under was a bulletin from nissan for the fix which was to install a factory ground cable right under the MAF. Now has anyone heard of that why would a ground cable fix a leaky injector code?

Oh he is a fairly new nissan tech so thats why im questioning it... Haha
