hearing bubble like sounds coming out of my black sunshines exhaust after replacing intake manifold with FFRP (oem) direct from ford performance. intake went in easy but now getting a little shaky at idle feels like your sitting on the engine. and no idiot lights on, sensors are reading perfectly. i dont know if it is some DIY paranoia or if i need new valve coves/head gaskets or somethin.
