i am having big poblems with my motor it wont idle worth a dam. I have the idle set to 1500 or there abouts. It wont idle till car gets warm. Vac pressure is about 5-10 on guage. i did a boost leak tester found one problem and fixed that and nothing. I am hearing a wierd noise comming from the back or the enigne towards the fire wall under the CAS sensor. This is a 6blot swap into a 2gn 95 gst. I re did the whole valve train with SS valves and everything was new except for rockers and cams. I put that on in July and had no problems till about October is when this problem arrose. I am thinking could be a head gasket problem. Sounds like you can hear exahust noises comming from under the CAS sensor. I know its not the ISC motor i tested that. Plugs and wires good and also coil is good. O2 is good. Car runs perfectly fine excpt wont idle worth anything. If someone is willing to come out and work on the car for me im willing to pay them to fix it substanially. Or knows something simple how to fix cuz i dont have time for anything major. Thanks

Low vaccum, Odd idle until cold...sometimes these symptoms point to a leaky FIAV. Either swap your TB with another one or try this mod:

It's a good mod to do even if it doesn't fix your issue. One less chance for a leak for both vaccum and coolant.

A compression test will tell you this.

my friend had the same problem. The intake manifold was loose on the head. He tightened up the nuts and the problem went away.

sounds like you have a vacuum leak, check all of your vacuum lines and your intake manifold...........hotwheels of turborides

actually i think it might be my intake manifold that is loose never thought of that ill have to get under there and look. if it was loose could you hear cylinder noise comming from it?? thanks guys

welp its was a loose intake mani fold causing bad idle and compressor surge as well. Just tightened some bolts and added one and fixed the problem thanks guys
