cisurfer

this all started after i did my egr delelte. before that i took off the lower manifold due to the non replaceable gasket leaking coolant and used rtv which fixed the leak. while doing that i cleaned all the intake runners in the manifold and the heads with carb cleaner and toothbrush they were nasty. I also replace the o ring on the injectors and cleaned them. installed new intake to head gaskets, new plenum gasket, egr gasket along with the delete plate, iac gasket. re-routed the vacuum lines so it emliminated the egr vacuum lines. when i give it slight throttle it whistles breifly then stops and then when driving it will whistle with partial throttle. I have a c&l plenum, bbk 75mm tb and bbk cai. i know ppl say this is normal but this just started since all this and ive had this setup for 2 years without this problem so its not normal. ive sprayed carb cleaner to look for vacuum leaks but i cant find any its driving me crazy
