No I am checking the coolant temp with it the cats fine

 

Ok then, that's what I'm asking. How do you know it's fine? (the cat)

 

b/c i drop the y pipe plus it not acting like it is bad or making the funny noise that it dose when they do go bad

 

There is no set noise they make when they are bad. So you dropped the Y and took it for a ride?

 

Yes it dose the same thing just really loud lol

 

So this is what i just did to test the coolant temp sensors, i hooked up the snap on scanner and watched the live data screen and watched my temp go from 72 to 189 and i watched my gauge on the dash. I dont think it could be any more dead on. Some thing i did notice though it idle fine till it got to 180 ~185 about and the loopy idle started and i kept checking the fuel snyc while it was warming up and notice it was at 0 to 3 the whole time till the loopy idle started then went to 14~15. It also cant stay running more then 30 sec or so b/c of the idle.

 

Look at what i found MMMMMM makes me want go run outside

How old are your O2 sensors??

 

Not that old maybe a year

 

If you are referring to that link as far as the vacuum leak. I could have sworn you mentioned that you checked everything. Too many threads, too much reading to remember. I too would check all the vac components and lines, etc.... If for nothing else, than to eliminate it. Just like the clogged cat.
