John Martin Posted October 31, 2006 Share Posted October 31, 2006 I recently replaced my valve cover gaskets, but have a lingering "whistle" in the intake area. I am assuming that this is just a vacuum leak that I haven't located yet. I have noticed a number of symptoms that may, or may not, be attributable to this leak. 1) Declining idle. I did not (stupid me) clean the IACV when I had the intake plenum off. 2) Weak acceleration. Car seems very sluggish 3) Shifting sometimes at very high RPMs and/or slow to downshift under load 4) I have a small coolant leak from the hose under the EGR valve. What symptoms would this contribute to? Any advice is appreciated. JM Quote Link to comment Share on other sites More sharing options...
