flashing SES at WOT

i was on my way from school today and i hit WOT then my SES started flashing.
i went to autozene for free check and guy gave me couple codes
P0301 cyl one missfire

P0325 knock sensor

P0141 downstream oxygen sensor heater
NOW. it is possible that only bad o2 sensor can cause other codes which i have??
btw. i had bad oxygen sensor couple times but i never had that ****ing missfire

blinking CEL indicates a misfire. I think you have a bad coilpack(s) The 02 probably caused the KS code

i would reset the ecu and see if it comes back first

i know there is a big issue with coil packs in 99 maximas.
i hit 80k miles this year so is it that time when they go bad?

I'm on my second 99, both five speeds, both had coil pack problems - the first (GXE) happened while under warranty, then when I bought the SE-L, I got the blinking SES under WOT. Got used coils from a 98 (rear bank) from a fellow org'er, & it did the trick, hasn't happened again. Used coils from a different 4th gen year is a cheaper fix than new, from my experience.

While out for lunch my SES came on (stayed lit).
I went to "Advance Auto" for free check and guy gave me 3 codes...

- knock sensor
- knock sensor
- 02 Sensor - Bank 1 sensor 1

What do you think that means ???
& why the knock sensor twice ???

switching coils does not always help. check intake for leaks, then probably replace O2 sensors. i have a ses light go on everytime i change spark plugs, probably because of exaust gases either to lean or rich, especially if your like me and go back and forth between bosch and ngk. for that sake if you want peace of mind buy dealer parts....
