I am looking at a 60k maint. and the shops want $750 to $850. Can someone help me with the details. The biggest thing is changing the plugs for me, as half the plugs are tucked under the dash. I can't find the PCV valve. The trany flush should not be a problem. If I did change these item, is there anything else to it like plugging the engine into the computer that only the shops would have? I am a schedule A driver.
