Bucking van

[MrSuhSpence]

I have been having this weird bucking feel when driving my 97, ses light on with p0300. I decided it was time to do a tune up as the parts were over 3 years old.
It still does it though. But it only happens in sub 60% throttle. I give it more gas and it doesnt buck at all. Anyone experience this? It's probably the injectors but I'd rather see something cheaper to replace

Bucking at part-throttle.... YEP been there done that! Several times!
Idle fine, full throttle fine.. part-throttle = bucking.
Common problem.
Both times mine turned out to be a worn distributor.

Here's my own video of my failed distro (that caused bucking)
