code 9=cylinder sensor where is this sensor located is it the dizzy,also code 74 misfire on cylinder#4 spark plugs r new,wires are new,injectors are new,am i missing something wit this code i need some help thanks alot guys

 

I am no expert and i am not sure, but man i think that ur piston #4 is about to pass away... re-check with sum1 else but if u think about it all the check engines are about a piston, and code 74 specifies that is piston 4 we're talking about.
