Ok. Tks for your help. Will post with result when known.

Thanks for your prompt reply trentmeyer23. No, I have not and what would be your recommended cleaner and procedure for this? BTW, I am not a motor mechanic just a do it yourselfer. But I can follow easy instructions.

When completing a one hour or more drive open road motoring when stopped the motor does not idle at normal revs but around 1500 RPM up and down in the rev range regularly and sometimes sounds like it wants to choke out. Water temperature is normal. Turning off the motor for a few mins and restarting sees the idle normal at normal revs. This never happens for city driving always idle normal at traffic lights etc. Anyone with some ideas of what maybe causing this annoying problem? Thanks.

I not fussed with Windex and I use ArmorAll Glass Cleaner.

Toyota 2001 V6 Touring. I am replacing the original audio system with an aftermarket Pioneer double din system (no screen). All wired in (except for the powered antenna) as I do not know what color cable to connect to in the original wiring harness for the auto antenna operation. Can anyone help with the color cable to connect to or a complete wiring diagram for the original audio system with auto antenna operation. My thanks in advance for any assistance.
