HAHAHA! You know that feeling when you're rackin your brain over something for so long and then finally you come up with such a simple solution that you feel like an idiot? You've got that relieved feeling yet you're mad you didn't think of it sooner... Well, yeah.. That's me. I had a leaky intake manifold. I'm positive that's the way it started. But sometime in the multiple times I tried to fix it I un-fixed something else. On the passenger side of the intake manifold, just behind the throttle body there's a metal tube that goes from there to the bottom of a coil or something... I say or something cause i'm not exactly sure... wires for the passenger side injectors come out of it.. Anyways, what happened is there's a flimsy metal flange to hold this tube in the manifold and there's a teeny little gasket to seal it up. In my multiple intake fixings I must have bent that flange, since it is only held in with 1 bolt (though the flange has two holes in it) and it didn't seal. After using rtv to seal the intake manifold to the heads it still leaked. This is when I got suspicious. I could hear the air leaking, so I stuck my finger all over and I found the spot. So with a little help from my dad we got it back in the hole and the symptoms stopped. The funny thing is it had the same exact symptoms as the leaky intake manifold gaskets. i'm so relieved now... Now just to the third door window.. See yall later
