I believe my 2001 ex sport has a leak in the intake manifold gasket, but I haven't been able to find it. I went all around it with carb cleaner trying to change in revs with no luck. Heres the symptoms, the usual 0171 and 0174 codes and when i rev it at the throttle body i can hear a sucking noise. It sounds similar to a secondary on a 4bbl carb kicking in and suckig in air. This is with air intake and all that attached. I also noticed the elbow attached to the valve right behind the throttle body on passenger side keeps collapsing at idle. When i rev it opens up some. Is there any one place that the gasket is prone to fail? Might help me to find the leak if I have a better idea where to look. Thanks.
