i removed the air silencer today and thanks to all the posts it was a very easy job, after this was done i took the car for a ride and in about five minutes experienced a bucking and rpm fluctuaion of about 50 to 75 rpms. this was very similar to the same symptoms i experienced when my cam sensor went bad, was there a step in the process i did not see about removing the silencer. will unhooking the battery do any good? thank you for your help. p.s. after arriving at our destination and staying about two hours the car drove just fine going home, about ten miles.
