ok so i recently put on a bbk x pipe w/cats and the car has felt great.. quick and torqy, but i today on the way home from work it felt really sluggish, like not pulling at low rpms like it usually does, i cleaned the throtty body and got all the carbon out of it, cleaned the filter and completely dissembled and put back together the intake, cant figure out the problem, could it just be me?

what kind of intake manifold you got? Do you know if it was ever replaced? If you have a stock intake manifold it may be cracked. Mines cracked right now and when i bring her past 3k rpms she starts to buck almost. Feels like powers not getting out right.

It took me a while to find my crack too. Anyway, i got fed up with the fact that i was loosing coolant and couldn't find it so i just devoted a morning to finding it. Mine was on the back of the manifold, one of the back coolant inlet/outlets leaking, seal was cracked. I found it by tracing coolant up the passenger side of trhe block onto the manifold.

ya its a stock manifold and i didnt see a crack anywhere, and i dont have the coolant problem, but there is a clanky noise when i get down on the gas...
