hey guys, i dont know very much about the rotory motor. i was just looking under my hood when i found 2 things that i felt were not right.

first thing:



the second thing:




for the first picture, somebody please help me find out where that thing plugs into and what that is.

the second picture, i have no i dea what that is and why its there but somebody please tell me why thats there and what its function is

Thanks alot!!!

 

The hose is what feeds pressure to the 5th/6th ports to open them. It should be connected to the air tube just to the left in the picture with the check valve in it. Second thing, I have no idea!

I'm no n/a guy anymore, those pics are a little too big to see the whole thing, but I think it goes to the split air tube that goes to the cat, it should have a small nipple on it.

 

What kind of camera did you use? Those look like AUX port lines.

 

First thing:

+1

2nd thing:

You can't tell in the picture what the cord you're holding is connected to...unless it's connected to the O2 sensor directly behind it in the photo. If it is the O2 sensor cord..the plug must be mangled... it plugs into a white plug between the firewall and the TB......at least it does on MY car, lol. A better pic would be helpfull.

 

i need a bigger pic....

 

holy ****...im blind!!!
to big!!!

 

can't see, pics too small.

 

and that O2 sensor needs to be replaced... it is probably shorting out directly to ground

 

lol noticed crappy MPG and power lately...you answers have been solved!

 

holy crap... thats my o2 sensor?? =( damnit.. i knew there was something wrong with my car. haha. damn.. how much do they go for? can somebody post a picture of the o2 sensor and where it should go? thanks!

 

That little plug looking thing in your exhaust is the O2 sensor, buy a new universal one from Advance Auto or RicerZone due to the fact apparently somebody already spliced your harness apparently...

 

damn, got bigger pics ?

 

This is the O2 sensor I bought..It has the factory plug on it so there's no splicing required.
