So my 2003 spectra is throwing a couple codes,

P0325
P0304


Check engine light just came on a few days ago, I believe the P0304 triggered the engine light because the car has had the P0325 code for a while.

Symptoms:

Rough idle @ startup (misfiring I assume)
Hesitates for a few seconds when first trying to accelerate (still misfiring I think), then runs fine
Seems to run fine after the initial rough start up and hesitations

It's weird because it runs really rough when I first start the car, and hesitates for a few seconds when I first hit the gas pedal to accelerate. But after I get on the road, it seems to run fine.

Codes are for a Cylinder #4 misfire & Knock Sensor 1 circuit fault

Any suggestions? Spark plugs are new, haven't changed the wires though. Should I get a new knock sensor? Not sure how bad this is for the car, my other car has a bad wheel bearing, my luck has not been great lately :)

Thanks for any help guys, would be greatly appreciated.

Any help or suggestions of where to start would be great my KIA brothers!

My idea is replacing the knock sensor and spark plug wires first, just wondering if anyone has more knowledge than I do and can fill me in a little bit, do knock sensors usually go bad on these motors?

etc, any help appreciated, thank you!
