I've been going thru the engine compartment in an effort to track down a miss at idle speed, the engine repair FSM ,page 8-7 step three , specs. the ignition coil resistance at 0.5 -0.7 ohms , the results i came up with were 0.9 -1.0 ohms .

the coil resistance here is too high , will this create a miss at idle speed? , either wy could someone please tell me what is taking place here , it does,nt seem that a coil would just wear out , and i'm considering wether to replace or not.

Any leakage out of the coil? I've had that problem before, and it caused a miss at different points in the RPM range. Mine was a slow leak that had no problems at first, but worsening problems over time.
no leakage that i can see.
