Here is something that I finally found out the hard way. the first thing I would check for when you have bucking, bad idle, ignition issues, or any sort of drivabitly problems or TFI's cooking up, CHECK THE ENGINE GROUNDS!!! After 2 seasons of fighting with my car and spending tons of money, my issue was a bad engine ground. I installed a separate temporary copper 4 gauge ground wire to the distributor hold down nut and right to the negative side of the battery and BAM problems all gone with the smoothest idle at 750rpm with a F-cam with no lope or surge and the cleanest ride ever. Its like nite and day. now all i need is to replace all the original grounds with new wiring. hundreds of dollars and stress all caused by a faulty ground. hope this helps others. I am so happy now
