Hey everyone, today while i was checking my fuses for my car amplifier I came across a disconnected hose on the air intake. It doesnt seem to effect anything to much as the truck runs normally, but its got me worried. I took a couple pics, hopefully one of you guys can help me out. Thanks

 

I believe it's part of the a.i.r. system- air injection reaction. it is used to feed air into the exhaust to help reduce emissions like the much reviled, and oft disconnected, smog pumps and diverter valves did with the carbureted engines. the system may work as it is, but may fail the visual test at an emissions test facility.

 

The other problem is that hose being open like that allows air into the intake and bypasses the air filter. It wont effect the short term driving, but it's also an large open air leak; the air still passes through the AFM, so it wont change the way the truck runs.

 

Any idea how i would reconnect it? I can't figure out what its supposed to thread into.

 

it doesn't thread into anything- there should be a plastic toilet-float looking ball thing below the throttle body that it clamps to.
I'd love to get you a pic, but my camera doesn't zoom 3000 miles...
