Ok this may be a bit of a dumb question, but does anything besides the sensors plugs need to be connected to the TB, I see that the passenger valve cover routes into the TB as well as the coolant. but is it necessary, can I leave all the connections open (pluged) or is there a few that need to be plugged into it?

Thanks

 

I would plug the breather line from the valve cover into it, just but just bypass the coolant passages. Also, if you have the charcoal canister, it connects to the front of the TB under the throttle blades.

 

nope.

I deleted the following emissions stuff (out of PCM as well)

EGR
Charcoal
Cats
AIR

So I should still plug the valve cover into the TB ...?? not use a breather?

also my TB (being roadmaster LT1not sure if that makes a diff) has 3 ports on the passenger and 1 on the driver.

so in essense do I need to connect anything to the TB for the sensors to work, or is that what your saying with the tube going from the valve cover to the TB port,?

 

bump

 

Yeah the only thing I would connect is the breather line if you don't use a regular valve cover breather filter. If you decide to use a breather filter, plug the port on the TB and you'll be good to go.

 

cool, looks like im pluggin up all the TB connections.

thx, Texas.

 

No problem.
