98 4runner still bucking

Glad the cleaning worked out. I've bookmarked witchhunter's page for future reference. I love seeing threads that are actually solved when the issue was as bad as this.

Glad I finally found this. Hopefully the OP is still around. I have this problem now, only happens at highway speeds. I'll be cruising along just fine but any sort of uphill incline it starts bucking (stuttering) I have to back off then get on the gas a little harder to get through it, but once back to speed if I'm on any kind of incline it does it again. I've researched and came up with so many possible solutions, plugs and wires, injectors, coils, fuel filters. I would send my injectors off to witchhunter if it wasn't my daily driver. Based on what you found and what you've learned where would you start?

Thanks
