hey heres the problem:

while my car is idleing warmed up i can hear the misfire. every few seconds it will pop continuously then stops then again it will startin popin not loud or anything jus as though it was skipping spark.

but i have chagned my fuelfilter. i had msd took it out and put in another stock dizzy, it got a lil better but now its jus as bad as it was b4. i also put new plug wires.
i even check the filters on the injectors.
i checked the ignition timing its dead on 16degrees
could it happen from jumped cam timing?
or
and injector being clogged or fuel pump?

my wideband reads rich all the time so i dont think its leaning out i really dont kno.
today i was at the track and under accel the car sounds like a wrx for a few secs untill it starts to accel normally.

LET ME KNO WHAT U GUYS THINK, THANKS ALOT IN ADVANCE

Try a new rotor and cap
Check timing

Rule out timing,

start from the basics, plugs, cap & rotor.

how old is the OEM dizzy?if it's like 10years old or more. It may be a good time for a rebuilt dizzy if your planning to keep the car for a while.

Next would be fuel injectors or the signal they're receiving.
