Hi,

I have a 99 SVT with 40400. My CEL reads PO460. I have an extended warranty, but it does not cover diagnostic feels. Is this something I should pay the dealer $200 to diagnose and then have the warranty pick up the repair?

Also, my car idles a little rough and sometimes idles around 1500-2000. Should I have a tune up, clean the IAC, have the IAC replaced under warranty?

Thanks,
Brad
