Hi Scotty ive been stumped on why my car is jerking or bucking. Ive done alot to it ive redid the timing for both the crankshaft and cam shafts. I did take the distributor off and spark plug wired so i had to refer to the book for my car. And as far as my knowledge the car is in time. I also did put a cold air intake but decided to put the orignal back on amd still had the same problem. They have ngk spark plugs but they were in before I started having any of these problems. When the car is started and idles it sounds fine. But when you put it into gears it sounds wierd like miss firing like the timings all messed up. When in first gear and lighly pressing the peddle is will jerk back and forth unless you slam the peddle. Also and time you switch gears or go to apply pressure on the peddle it will take a second to register and then it will have a sudden jerk. Would love some advice thank you. Also love your videos keep up the good work. Hope to hear from you.
