95 tracker miss after warm up

[1995 toad]

I have a 95 tracker that I think has a lean miss after warm up new plugs wires cap rotor air filter fuel filter 150 ish all cylinders belt is good bolt is tight fuel is 35 start 31 run no cel tps tests all good does same miss with o2 disconnected idles great and runs good until it warms up then it has an intermittent sporadic miss. when it misses the injectors make a clattering sound instead of the crisp click at idle when listened to with a stethoscope.  cant figure this one out will be pulling the ecu to check caps.. I need some advice. thanks in advance
