1996 Geo Tracker P0300
#2
oops clearing the code, cleared the freeze frame, but.. next time....
freeze frame shows you when the random all 4 cylinder misfire happened, speed,rpm, load, etc. is the misfire cold only? or hot, both, or idle, or , cruise?
if you knew the when you could watch O2 and see whats happening live/
bad coil
lean mixtures

id plot the 02 front sensor as graphic and drive and see if its going lean.
if its rich misfire, the o2 goes lean when not. do to air slugs.
if the coil fails, all 4 misfire, and you get 4 air slugs of 20% oxygen to the header. the 02 rails the hard lean, stuck at 0 volts.?

good luck to you !
