what is normal idle rpm when the car is fully warmed up. mine is 900-1000. i also have p0300 p0301 p0302 codes. think i need a vavle adjustment and new front O2 car 04 S with 52k miles

 

that sounds about right for normal idle. although if memory serves me right those are mis fire codes. look for the misfire thread and get those lights off first before you do anything else. and if your front o2 sensor went out there was a TSB for the O2 sensor getting too much condensation. not sure if it applies to AP2v1, but regardless check it and see, because you may be able to get a new one for free from the dealership. the PDF is here somewhere.

 

now that tsb is only for 06+
