where on the intake is the leak? at the top split gasket? I found one small leak on the drivers side ground wire on the long intake bolt. There was air sucking past the head of the bolt because the ground wire had a slot in the eyelet. I moved it to the fuel rail bolt and it seems to have helped a lot.
I listened today a little bit with my stehoscope/hose and did not hear a lot of noise. But that was when it was cold. it seems my rough idle is only after warm up.. which leads to vacuum leak.. as things expand and rich warm up goes away. I also used ether and sprayed in the area of the leak and it almost killed the engine.
I changed my plugs to cheap bosch platinums and blocked of the egr with a plate.. no change. other than i have a code now i have to check since engine light came on.
more later.....
