i recently finished installing a set of bc 264 cams and now having some idle issues. it sits around 850rpms at idle, but the motor seems to vibrate very bad and the boost vaccum seems to fluctuate sporadically between 6-7.5, which it didn't do prior to installing the cams. at times, it also feels like the engine is bogging down and about to die. during my test drive, when the car is in motion, it pulls strong and feels fine, but when slowing down or coming to a stop, the car died a couple times. any suggestions on what could be wrong??? thanks for any help!!
