Could someone point me in the right direction in regard to which vacuum lines to start with. I know there are 2 formed small plastic lines that run from a ?device on the front right side along the front of the intake and goes to left end side and one goes on to something under the air filter boxes. The connector ends on these are virtually non existent, but I have not been able to find a correct photo/listing to order new ones. Anyone with a 96 MUST know what I am talking about and just what the hades it does in the first place.............I know there must be some HUGE leaks concerning this hook up, but the dealer in my area has not been a lot of help in the past......Ideas and pointers anyone....??

It sounds like you are talking about lines that go to your charcoal purge canister and possibly your trans modulator. You dont have to order these parts. If you are refering to the rubber parts then all you have to do is go to auto parts store and tell em what size you need. If you dont know the size then ask one of em to come out and look at it.

Then the ones that have a sharper bend in the hose just make sure you cut those longer. You can get a set of small needle nose plyers to stick into the new rubber hose and stretch it out before you install it because some of them are a bitch to put on.

Ok just a trick I learned to find a leaky intake...
Not the safest way.. With the engine running (idle) spray starter fluid near all the seam line around gaskets, hose fittings etc. just a little bit, what your looking for is a sudden increase in speed.
Go slowely around any suspected gaskets or vacuum lines . If the RPM'* surge go back untill you find the spot. Worked for me more than once on leaking gaskets and lines..
Be careful with the starter fluid and the nuckles in the fan and belts.. One of those spray tubes helps.

Good Luck BB
