About 20 years ago, I rebuilt the entire top end including cam with all new aftermarket parts. I have a 92 lx 5.0. When it was complete n back on the road, I have this bucking issue in lower gears. I have lived with it and just worked the clutch n gas to settle it down. I was told way back when that it’s was kind of common issue for what I did. The solution was to get a custom burnt chip and that would fix it. Now years later, I am curious if there is some type of plug n play, that would eliminate this problem?? Any help or advice would be greatly appreciated!
