Hey there guys, i need your help. A few weeks ago my rear lines going to my rear heater busted so i replaced them. Stupid me, i forgot to mark which ones went where when they ran down from the engine bay underneath to the floorboards. I marked a picture of there where abouts to show exactly what im talking about. Though im sure you all know.

My reason for asking is i connected them up remembering and mocking up the old lines best i could, but ever since i have had this wierd idling issue since when the heat is on. So, im assuming i hooked a supply to a supply or something of that nature, My heat works great though which wierds me out.

If you can just snap a picture of which lines in the engine bay go where underneath that would be greatly appreciated. Thanks alot guys. !!

They come up from underneath in this general are here, they run along the passenger side frame rail.

I can get you a picture, but it won't be until tomorrow morning. I'll check back in and see if someone hasn't already posted one. In the meantime could you tell me the stats of your Runner? Year, model, etc etc.

You probably have air in your cooling system from changing those lines. That can have an affect on the idle air control valve (IAC) which is partially actuated by coolant flow/temp. You can purge the system of air by jacking up the front or pulling up on a curb, pop the radiator cap off (not when it's hot of course), and letting it idle for 10 or 15 minutes. You are essentially making the radiator cap the highest point in the system in hopes that any air will make it's way up and out.

and thats why Brian is awesome, he can take that tiiiiiinnnnnny little photograph that no one can see and figure out what the heck is wrong! LOL I have a hard time remembering where the oil goes when Im looking at the real thing, let alone a pic the size of my fingernail!
