129K miles check engine diagnosed by local Mazda as miss fire on
cylinder #1. I replaced fuel filter, MAF (junk yard), 4 plugs out of 6
replaced (other two this week due to angle), replace all spark plug
wires and an oil and filter change. On idle it feels like the engine is
missfiring (I have spark on all wires as I tested at the ignition block
via one wire at a time. The seems out of balance on acceleration. Ideas
?

cylinder misfire codes can be caused by any number of things, not just
plugs & wires.... although it's a good idea to replace those from time
to time.
bad fuel injectors, o2 sensors, bad valves, catalytic converters, low
fuel...even the computer..just to name a few.. hope this helps..
