I have these 2 codes. Which should I fix first? I lost my job after 18 years Tuesday and money is an issue.

thanks

 

go for the misfire, as i constantly hear here, KS is a ghost code, maybe the misfire is setting it off, my 2nd cyln misfire set off my KS, fixed with spark plugs, a new oil seal(to fix leak slight leak) and injector cleaner. i used them all at once to make sure i didnt have to go back to it. thats all i can think of, im sure more will come and happily give you their input.

 

yea 150,000 things can set off a KS code.

 

Missfire > knock sensor. If money is tight just stick a resistor in the KS harness and your good.

 

missfire 4 sure.

 

both are kinda critical.but i wud say misfire.

 

fix misfire, clear code, drive 100 miles or so, recheck for codes to see if knock sensor shows up again (it won't trigger the CEL alone)

 

Missfire it is. Thanks guys for all your advice.

 

Definitely misfire.
